  1. Looking for Back Grill, AT4 Badging and black dual exhaust tips. I have been jonesing for them since I picked up my white AT4 3 weeks ago and then recently saw pics of all of them on a grey AT4 from a dealer site in Florida. It l poked really good and confirmed my need. I am thinking the grille may be from an Elevation model. I saw some black AT4 badging on EBAY but unsure about quality. Any help would be greatly appreciated.
  2. I'm looking at the Flowmaster Outlaw Dual Exhaust System. I do like aggressive exhaust but my main consern about the outlaw is it too loud to have a conversation in the truck with windows up? If it's too loud how would the Flowmaster FlowFX Dual Exhaust System with Black Tips; Middle Side Exit suffice?
  3. Well, paid $80 to get the muffler and flapper cut off on my 19 with the 5.3l.. The drone is pretty bad and it sounds a bit too airy. At idle it sounds great, same with hard acceleration. On my 14 with the 6.2L, this mod sounded great. Should I have kept the flapper? I thought I read plenty of people who said save money do a muffler delete. What can I do to help this out?
  4. I have a 2012 GMC Sierra 1500 with 2.75" exhaust pipe. I am wanting to delete my muffler and add a glasspack without welding. Problem is, I can't find any adapters to fit anything. Do I go with a 3" or a 2.5" glasspack? And whichever one I go with, what size adapters/reducers do I use? The muffler shops in this area charge around $350 for this work, so that's the reason for doing it myself. I appreciate any help given!!
  5. I was hoping after SEMA we would start getting some sneak peaks into what was coming for the 3.0, but no luck thus far. Anyone else heard anything? Nothing much from what I have tried to research.
  6. Hello everyone, I currently have the GM Borla Performance Exhaust on my 2018 6.2L and I want more sound. The guys at muffler shops recommended I replace the muffler with this one: https://www.holley.com/products/exhaust/mufflers/street_chambered_mufflers/40_series_original/parts/430402 Part number:430402. I am aware that my current system has a flapper which eliminates drone but would that carry over to this louder muffler?
  7. Replaced my stock exhaust ('19 Sierra, 4WD, Extended Cab) with a Borla. What the hell do I do with the stock exhaust? Can't envision a need for it anywhere. Just hold on to it or is there a market for stock gear? Just looking for suggestions so it doesn't sit in my garage!
  8. Trading in truck and looking to sell the exhaust I had on it for about a year. It’s in great shape. Asking $650 with shipping costs paid by me. Part number is 140550BC on borla’s website. Pm or reply if interested. Located in Orlando, Fl if anyone wants to local pickup and avoid dealing with shipping. IMG_3932.mov
  9. So I'm getting a leveling kit installed on my truck soon and thinking about running 33x12.55R20. Anyone running 33's and how does your shift points feel? Also is anyone making an exhaust for the 3.0 duramax or a tuner? Any information will help.
  10. Cutout system installed on my Trail Boss
  11. I swapped out my sto k muffler for a carven tr and ran new 3" piping to a single exit exhaust. Although it sounds good around 1600-2500 rpm it's just too loud especially with a baby in the truck. With the stock resonator it's just too quiet. Has anyone tried a aftermarket resonator like the vibrant series just to take the edge off the exhaust without sacrificing too much. Thank you
  12. Installed the borla type-s exhaust couple days ago. build quality is excellent, fitment was absolutely spot on. took me 5 beers and about 2 hours... my thoughts.. on the system... also have a type S on my SRT... 1. Cold start is aggressive! It literally barks.... I was very surprised by this, much louder than my SRT system... 2. After engine warms up and rpms settle down it has the very standard s-type deep burble at idle. If the truck is parked and just running, walking behind it is just music to my ears. Very deep little burble that just sounds great. 3. As you ramp up the rpms and roll through the gears, the sound is deep and pronounced, this is the loudest type-s exhaust I’ve heard. Not in a bad way, just know that you will hear this exhaust unless you absolutely butter the throttle and accelerate like an old woman. 4. No drone in 9th or 10th gear.. no goofy noises or vibrations with cylinder deactivation stuff so that’s a major plus. conclusion happy with the purchase, louder than expected but still nothing too crazy. Getting the ATAK version would be overboard for a pickup in my opinion... engineers at borla said their touring style is identical to the gmc branded perf exhaust in regards to sound output. so their 3 levels are touring- tame type-s - pretty big jump, aggressive! Crazy cold start that barks atak- crazy man over the top sound, I don’t think many guys would go this extreme will get better videos soon
  13. Hello all, So I’m currently running the 12909 Magnaflow 3.5” 22 inch muffler and have been eyeballing the Magnaflow 15278 catback system for the RCSB Sierra. The problem is that the catback comes with an 18 inch muffler rather than a 22 so I expect that it’d be louder, but by how much? I currently really like the sound of the 22” muffler while running LTs and a catless y-pipe but I’m afraid that if I decide to fork out money for the catback it would just be way too loud. Anybody ever used an 18” inch Magnaflow with long tubes?
  14. Hey all, Comparing exhaust and I am having a hard time figuring out what I want. I have a LT Trail Boss. Reply with what you got, opinions, interior drone if there is any, and a video is possible. Thanks.
  15. 2015 GMC Sierra 1500 SLE 31K miles. So I straight piped my exhaust and deleted the third cat now I get about 9 mpg literally went through half a tank in one day. Can anyone shoot me in the right direction as to why this is! My guess back pressure but I keep reading things that go back and forth about it. Long story short I just bought a new cat and borla atak full system to try and fix this issue. Running 93O
  16. 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.
  17. Finally received the Gibson cat-back exhaust (Part #: GPE-65692) after 2 weeks and had it installed a couple of days ago to replace my Magnaflow muffler. It’s a single-in, dual outlet stainless steel cat-back exhaust. Shop charged me a $100 install and they put 2 weld taps on each of the joints for when the clamps loosen over time. First start-up after install was loud, I mean it was barking. I was like, who the hell said Gibson exhausts were tame . It has a very rich deep tone to it. After driving it for a couple of days, the volume has mellowed quite a bit. Loving it. I have experienced the GM Performance exhaust a few times and I will say the Gibson is a touch louder. The Gibson is also a bit faster, more responsive exhaust. It seems it’s tuned for low revs. The 6.2 engine is not a very high revving engine but with the Gibson, it sounds a bit like the engine is revving faster than it actually is. I didn’t get that sensation from the GM Performance exhaust. Idle is dead silent, almost like engine off. There is very minimal drone on the highway. I actually don’t mind this. Just a little so you know it’s there. Diameter wise, it’s a little smaller than the GM Performance exhaust so not sure of any performance gains. I did it just for sound though. I paid $495 including tax and free shipping for this. I did already have a 10% off coupon from RealTruck. The bang for your buck is quite astonishing. Most systems available for this truck cost 2x-3x as much. It’s still on sale for $508 on RealTruck (https://realtruck.com/p/gibson-exhaust-systems/v/gmc/sierra-1500/2019/). I have no regrets, one of the best purchases I’ve made so far on this truck. As always, sound is very subjective so your mileage may vary but it’s hard to go wrong with a cat-back system for $500. Cold start-up below (didn’t quite capture as well as I would have liked). AT4 Gibson Exhaust.mp4
  18. While I was admiring the underside of my bran new 19 Silverado I noticed the exhaust pipe, immediately after the cat, is squished, like super flat... Has anyone replaced that section with a normal round piece of tubing? Did it make any improvements in sound/mpg? Seems like it must!
  19. Hi, Has anyone else noticed the smell of exhaust fumes from other vehicles in your cabin? I haven't noticed this issue anywhere near as bad in previous vehicles. Isn't the cabin filter supposed to filter out the exhaust gases? I haven't checked to see if it's even there(behind the lower glove department?). Is this normal?
  20. I have 2019 Silverado 1500LD stock to the bone. If install a cat back exhaust just a simple street 40 series flowmaster or a super10 flowmaster. Will it hurt my MPG? IF so do yall know by how much? I've never owned a truck I've only owned Camaros and Corvettes so this Pickup Ownership is new to me.
  21. 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!
  22. Trying to decide between a corsa or borla exhaust for the Silverado 5.3 with the dual rear exit. Not many videos besides the one corsa video on YouTube.
  23. So I have a 04 Silverado crew cab z71 4wd. I have a 2.5 inch lift, cold air intake, and 285/70/17 mud tires. I’m looking to turn my truck into a little bit more of a power house. I plan on getting all new spark plugs (need help with which spark plugs) and a whole new exhaust from the headers back. (Also need help finding that). I’m trying to get the most performance out of these upgrades as I can as I am getting a inTune i3 8245 Platinum + Custom DiabLew Tune as soon as I decide what spark plugs, and full exhaust system I plan on getting. I want the most performance I can get out of these upgrades.
  24. I just bought a 2015 GMC Sierra Double Cab 2WD 5.3L and I'm trying to find a full headers back exhaust system. If it helps any to tell what i like, I like the sound of my dads F150 5.0L with long tube headers and mbrp exhaust. I like loud but not obnoxiously loud. I like a nice sound of a V8.
  25. Hi all, Now that I am a bit older with a family, the days of extreme loud exhaust in sport cars / trucks has come to somewhat of an end. I have a 2016 GMC Sierra 1500 with the 5.3l. About a year ago I decided to try out the Magnaflow cat back 3" and had a horrible drone through pretty much the entire RPM range. I tried everything to calm the drone but nothing seemed to work. I tried a couple of Borla exhaust systems and still too loud of a drone. I wanted to share a new cat back exhaust I just had installed that I am more than pleased with. The exhaust is handcrafted by MRT Performance in Plymouth Michigan, near where I live. They use T304 piping and they spent a lot of time developing and perfecting a bad a$$ muffler with a drone rating of 1 out of a 10 scale. Meaning 1 is almost no drone. The exhaust tip comes welded on and nice exhaust clamps are included. A buddy recommended them to me after my numerous failed attempts of finding a low drone, performance exhaust. I wanted to share this because I have read other posts about guys wanting performance exhaust but without the loudness / extreme drone. I have to tell you that I am so impressed and so relieved the drone, that was giving me headaches, is now gone! The low nice sounding rumble is there that at cruising speeds, and going WOT gives me that ear to ear grin! Normally I would not post about products I buy, but I had to share this newest purchase. The nice thing is I can have normal conversations at all RPM levels. The cool thing is MRT posted two nice videos of interior and exterior sounds using their Silverado test vehicle. I purchased the MRT Deep & Mellow cat back. They do ship their systems too. I attached some photos of my truck with the completed system in place.
