  1. What do you guys think? It's not as loud as a full aftermarket exhaust would be but I think it sounds pretty good for the money I paid.
  2. Needing to install a 3" glasspack on 2.75" exhaust. Can someone please give me some help with suggestions on a good way to get them clamped on? I don't want to make it permanent. 3" ID/OD don't fit, so I'm at a loss. And I'm told not to put the muffler over the pipe. Do I need to go smaller?
  3. I’ve been having some issues with the exhaust system I built for my 2015 Sierra 1500 5.3. There is way too much drone. I have TSP long tube headers with a catted y pipe going to a manual exhaust cutout, then some pipe, a flow master 50 series, more pipe, then turns out the side before the axle and sticks out maybe an inch past the quarter panel (all 3in pipe). The muffler could be moved foreword or back. Also I don’t have an exhaust tip. With the cutout closed it is not very loud at idle or on the throttle but when cruising it has a terrible drone. It’s very annoying. Because of this I’ve been leaving the cutout open all the time. With it open, it’s very loud and I have to watch it around cops but cruising on highway it isn’t annoying and it doesn’t have any drone cruising. I’d like to modify the system in two ways. I want to get rid of the drone and I want to switch to a louder muffler, probably a glass pack. The 50 series it way too mild for me. Any suggestions would be greatly appreciated.
  4. Hey everyone, I need some advice! I've spent countless hours using the search function, sending PM's to members (and you guys don't need to respond again if you don't want to), and listening to YouTube videos (which suck because you can't hear what they sound like from inside the cab going down the road)...but I still can't make up my mind! I want to do a muffler swap on my truck (details in signature). I don't want to spend the money on a full cat-back system...I'm just going to swap the muffler and cut the factory tail pipe so it dumps over the rear axle. I want the sound to be deep and aggressive under acceleration....but close to stock (no drone) while cruising....and without any goofy stuff going on when it switches to V4 mode. My budget is around $200. I've narrowed my choices down to 5 different mufflers....and will explain my concerns & reasons for hesitation with each one. In no particular order: Magnaflow 22" 12589 - I'm concerned about it being too quiet (unless I'm at WOT) for people to even notice, and also worried about drone while cruising (I've heard too many people that complained about magnaflows having drone) Borla Sport 19131347 - I'm concerned about it being too loud in the cab while cruising and switching V8/V4 (or just too loud in the cab in general) Borla Touring 19131346 - Basically just concerned that it's going to be too tame, and I won't hardly be able to tell any difference from stock. Not worried about the drone with this one though. Dynomax VT 17949 - I'm worried about the spring/valve assembly breaking or rattling...and having to get it fixed or replaced after a short period of time. I like the concept, but the moving parts make me nervous. Dynomax Ultra Flo 20" 17233 - Can't find a single sound clip of this muffler on a 5.3; worried about drone and V8/V4 noise I would appreciate any advice (or sound clips) you all can provide. I'm a nervous wreck over this situation, and I can only afford to do this once! Also, please skip the comments about Corsa (I know they're awesome, but I refuse to spend that much money on a muffler) and straight pipes (been there, done that...over it). Thanks in advance everyone!
  5. Hello, I am looking for recommendations or advice regarding the Flowmaser 40 series single out muffler. I am wanting to remove the adaptive valve on my 2015 V8. If I cut off the valve, replace the muffler, and leave the resonator, will I still get the Flowmaster sound? I wouldn't mind a deeper sound, but I don't want it to be too loud either. Just trying to find that happy-medium. The main reason is because I am getting the "chirp" or "squeak" from the adaptive valve. My AFM Disabler helped with the chirp when switching from V4 to V8, but I still hear it when I crank my truck. Any info or advice would be appreciated. Thanks! Ben
  6. I have a Borla Atak Muffler that I just put on my truck a month ago. It has one month of usage. Sounded great and loved it as a Cat-back system. I Decided to do long-tube headers with cat-delete and that muffler is just too loud with that setup. So I have replaced the muffler and am now selling just the muffler. I would like $200 for it, plus $20 shipping to anywhere in the USA.
  7. Installed a 3" Motofab level on my truck last weekend. Rear is stock. Added 20x12s with 33x12.5 tires. Minor plastic and metal trimming, no rub at all. Smoked my tails and 3rd brake light. Will smoke my front turn signals and corner markers this weekend. Will also vinyl wrap the chrome mustache on the bumper, unless someone wants to trade for all black. Going to do a muffler delete (leaving resonators) and clamp the flapper valve open, will also add a Range AFM delete. Has 30% tint now, will eventually do 15% this summer. Will post more pics as I make progress.
  8. Ok, need some opinions, advice, ideally some experience. I've been through many many mufflers ranging from "Wake the kids across the house when you start your truck in the morning" to "is that a stock muffler I just spent $150 on?". I now have my first new truck ever, a 2018 GMC sierra 1500 crew cab all terrain with the 6.2. I love the truck and I'm looking to do a custom exhaust only because of the look and not the sound (maybe 75/20 because this truck has no tone at all). You get the idea...I want it quiet. The exhaust I want to build is a side exit, dual tip, before the right rear tire. I don't like the look of the Gibson setup and I'm concerned it would be way too loud anyways. I have a couple questions and would love thoughts and opinions. 1. How far forward can I go with a muffler without issues? If I do the corsa twin tip I'm going to need a lot of space due to the design of that particular tip (which I like a lot). Does moving the muffler towards the front effect sound at all? 2. If I want zero interior drone, what do you think about a big 22" magnaflow and right next to it weld in the factory rear resonator? That thing is straight through and if I had the room under there to do the pipework needed for the side exit, I would think that the combo could provide a little more V8 tone but tame it down considerably. I assume most of you will hate this idea but could it accomplish what I'm after? Thanks,
  9. I have a used Borla cat-back, Touring# 140570, local pickup only for $600 system has about 15k miles, great exhaust, not too loud, no drone. A bit dirty, removed because I am trading in the truck. also have Volant Cold air intake if interested for $200
  10. Hi, I'm new to this form so hopefully I'm doing this correctly. I have a 2017 Silverado with a 5.3 L V8 that also has eassist. I was looking in to different types of Mufflers I could get and I really like the Super 40 with dual output, but when I went to a Midas, they said that since my truck has a hybrid option installed that an aftermarket exhaust would sound horrible and not a big difference in sound volume. I was told that the Super 40 from Flowmaster would not be too loud but also not too soft. Has anyone tried a different muffler on a S Eassist Silverado before? And does a Super 40 sound too loud or just right? Something that would turn heads when your next to someone but not turn heads blocks away. Thanks!
  11. Hey guys I am planning to change the transmission fluid on my 2007 Silverado (New Body) 4.8 4x4 here soon. My muffler recently wore a hole into it and rusted out a piece of the exhaust. Therefore, I am planning on replacing my entire system with this one from Amazon. https://www.amazon.com/dp/B00503PU70/?coliid=I365UW575WJD1C&colid=1GQFQXGWZEWEY&psc=0&ref_=lv_ov_lig_dp_it Anyway I have done some research and it looks like the exhaust system prevents the transmission pan from being dropped completely. For this reason, I would like to change my transmission fluid and filter while I am changing out the exhaust. It seems like it is going to save me a world of trouble. Also I am coming up on 95,000 miles and almost positive it has never been changed before. However, there are a lot of opinions on both the right way of doing this and the wrong way. I see a lot of people on YouTube removing the metal line from the front of the transmission radiator and letting the old fluid drain out that way while adding in new fluid. Then they stop when they see new fluid being pulled into the container and replace the filter then go on with life. I have heard other people say that this is gambling with your transmission and should not be done. Basically any advice and opinions would be greatly appreciated. I also heard to not get sucked into "fancy labels" when it comes to new fluid either. My local guy said you want to replace the fluid with exactly the same thing that is in there right now as it was not designed for anything else. I just looked in the manual and it says that it is DEXRON VI so probably going to go with this from Amazon. https://www.amazon.com/ACDelco-10-9395-Dexron-Automatic-Transmission/dp/B01EKMGG92/ref=sr_1_2?ie=UTF8&qid=1526257467&sr=8-2&keywords=dexron+vi+automatic+transmission+fluid Let me know if you guys need anymore information. Any advice and direction you guys can give would be awesome.
  12. Hey Y'all. I'm in need of some advice. I just recently bought a 2018 Chevrolet Silverado with a 5.3L V8 and its too quiet. I wanna give it that nice low rumble at idle but have it loud when you punch it. I don't wanna spend a whole lot of money so i'm hoping to stay away from a cat back system and lean more towards an exhaust. Was also planning on keeping the V4 mode as well so if it has drone issues let me know. I've heard of lots of people doing a Flow Master 40 with a resonator delete? Seems to be the most popular. Thanks in advance for the help!
  13. Hi guys! I’Ve got an ‘05 Sierra as well as an ‘05 Tahoe. I made this video of the Flowmaster in the Sierra and plan to mod the Tahoe the same way. I made this video of the Sierra thinking it may help some guys decide which muffler they’d like to go with. Let me know what you guys think. Click for Video with sound clips
  14. I’m selling a Corsa Sport muffler only. $275 plus shipping. Only 1 year old...approximately 10k miles. SOLD. Thanks.
  15. Earlier in the year i did a muffler delete on my 2017 Sierra 1500 Elevation. Here's an interior video of the exhaust volume for those of you that are looking to do the same thing. Cheap way to get a good result!
  16. I'm sure this has been discussed somewhere else in the forum, but I cannot find the exact answer I am looking for. I have a 2015 Sierra SLT. I love the quietness of the cab, especially on long trips, but I really wish my truck had more of a throaty sound upon start up. Is the best way to achieve this just to get a new performance muffler? If so, what kind? I don't really want to remove any of the factory parts like the resonator if I don't have to, and I don't want an obnoxious sound. I just want it to sound like a truck upon start up. Any help would be very appreciated.

  18. Im planning on geting a new muffler for my truck with the 6.0. I want to keep it all stock with same pipes and cats. My question is what offset do I need the new muffler to have? Im planning on a Thrush 17649 Welded Muffler since im on a high school senior budget, and I know its not the best out there but its cheap and should get me through until next summer. Also about how much would it cost to have just the muffler installed?
  19. So I just purchased a 2016 Silverado 1500 LTZ and wanted to inquire about some upgrades starting with a killer exhaust system. Just wanted to see if anyone had any recommendations on what they prefer or what would be best system or just muffler to add on to the truck. I'm looking for an agressive but not over the top model that will catch peoples attention but not get me pulled over and piss off the neighbors. Thanks in advance.
  20. I'm in the process of purchasing a 2016 GMC Sierra 1500 5.3L and am looking for opinions on a great muffler. I would like it to be loud as possible with a great tone. I've had a Cherry Bomb Extreme muffler on a previous truck (2005 Dodge Ram 1500 Hemi 5.7 Sport) and loved it! Unfortunately, upon looking at the specifications, I don't think the inlet/outlet sizes of another Cherry Bomb muffler match up with the '16 1500's exhaust system. I'm not very educated with installing muffler systems so maybe there's a way around this, if so please educate me. I've watched numerous YouTube videos on Flowmaster mufflers and don't think any of them sound loud enough. I've heard a few in person and feel the same, too quiet. The only one I've been satisifed with is the Cherry Bomb Extreme. Any suggestions? Thanks.
  21. Hey, this is my first post so take it easy on me. Just have a few questions. I have a 2005 Chevy silverado 1500 z71 just in case that helps in any way. 1. Brakes - slightly squeaking / squealing more of a low pitch when breaking at lower speeds. not sure if just something like rust or anything, it is not a super loud screech so i'm pretty sure it isn't an indicator. Wondering if anyone knows what it could be. - Also, im not sure if it is maybe just how it is on that truck, but the brake pedal, I noticed when I press on the brakes, it kind of stays there for a brief second, and is able to move up and down a little without resetting back or pushing against and staying with my foot like most brake pedals seem to do. 2. Check engine code p0446 - have had the light go on and off for a couple of weeks. When fueling it cuts off at a little over 3/4 tank full. I believe it to be something clogged in that system based off of what i've read online. Wondering if anyone else has had the same problems or would know of what exactly to do. 3. Exhaust. - I notice the exhaust is 2.75" in diameter stock, which seems to make it more difficult to find any parts like exhaust cutouts or mufflers. Wondering if anyone has any suggestions for that stuff. Just looking to gather more info, get a better idea of what is going on, maybe learn from others who have had the same issues or resolved similar issues.
  22. I have a 2006 gmc 4.8 and just want to know what peoples thoughts are on cutting off the muffler and welding a pipe in its place.
  23. Already tired of the super quiet 2015s....Im looking at Borla xr1 and JUST replacing the muffler. Literally looking for somthing to just bolt on and do nothing else. Anyone done this? I dont have AFM anymore to worry about. Searched the forum and didnt find much in the long pinned post. I dont have the money for full exhuast anyways. What size inlet and outlet would be a direct fit? Also looking into muffler delete...
  24. Hey guys first post here... I recently installed a flowmaster super 44 on my 2011 gmc sierra crew cab 5.3. I had them dumped before the axle since it was cheaper than running tips out the back. I recently made a 5 hour drive home this weekend (im in college) and the drone was unbearable. I love the sound, but it is just too much on the highway. My question is will dual tips reduce the drone and highway noise? Thanks for the replies!
  25. So, a couple months back I installed the Magnaflow cat-back, single in/dual out, exhaust system on my 2015 2500HD 6.0L Sierra (see some info/pics on the install and outcome below). http://www.gm-trucks.com/forums/topic/171270-2015-60-muffler/page-2?do=findComment&comment=1673626 Truly I am quite happy with it. Got a great deal online, sounds great, was able to install it myself with no major issues, got the dual tips perfectly aligned, etc... Fast forward about 2,000 miles. Still love it, however after moving it in my driveway I recently noticed a 3rd wet spot underneath my truck about the same size/shape/color as what had resulted in water dripping from the exhaust tips. So, I got underneath and noticed that some water was dripping from both outlet ports from the muffler. Now, the drips on each side are coming from where you clamp the rear pipes to the muffler outlets. Worth mentioning: periodically since installing, I have gotten back under the truck and checked every nut and bolt for loosening and re-tightened where necessary. There was some very slightly that tightened more after about 50-100 miles but absolutely none since then. Also worth mentioning: the outlet ports on the rear of the muffler are basically exhaust pipe diameter and stick out roughly 1", which is what you connect the exhaust pipe to, and clamp down on. The 1" that sticks out obviously is not a perfect tube; the welding imperfections stick out 1/4"-1/2". I did not want to clamp the exhaust pipe down to only half, or the tip, of the outlet port, so it is partially clamped down over welded material. I believe this is obviously why there is some water leaking, but I saw no way to avoid this. I found the point where I thought the pipe was clamped on just enough to be as solid as possible, which meant MAYBE a few mm's of weld bumps, and tightened the hell out of it. My question: how big of a problem is this small water leak, does it largely effect backpressure, performance, etc.? I am not very knowledgeable on exhaust systems as my last one was done at a local shop, but the only solution I can see is taking it to a shop and having them weld those pieces together to eliminate this issue. At that point, might they as well weld each connection together? Anyone have any other suggestions? Any and all feedback or insight is appreciated. I am pretty sure I know what a shop will tell me to do, but hoping to get the real scoop here first! Thanks!!!!
