Isn't there a Corsa piece like this in the FS section? Might be 3.5" though.

 

I'm thinking of taking my Dynomax Catback (with Flowmaster muffler) off and putting something else on.

Yeah it is 3.5". How long ago did you order the magnaflow kit? Jw to compare to below...

 

I got the Dynomax pipes but it took me two months from when I ordered them until I had them both. I ordered the intermediate pipe from Summit and found the tailpipe on eBay. Also, I put an 18" Magnaflow on mine and I wouldn't go any shorter without the Dynomax extension pipe (51075) because you won't have enough pipe to clamp onto.

 

Interesting... How long ago did you order? I have been trying to piece it together like you did too but tail pipe was backordered 5-6 weeks and now backordered another "60-90 days". So went to buy a kit from Jegs and it is now saying the kit is back ordered too....... Can't win, pretty frustrating since I have this brand new magnaflow muffler and corsa tip sitting in my office. Really wanting to go with stainless mandrel bent!

Without searching all these posts has anyone on here run the 3.5" system Gibson makes for the 6.2 trucks? I have MBRP on my 2015 right now and this junk might make it another year or two before it has holes in it...... that's how bad it's rotting. It's embarrassing on a truck that otherwise looks great underneath except for this shitty exhaust. I am looking for an alternative to this and want something that isn't constructed from T409...... T304 is where it is at. Now Gibson says their tips are T304 but just say "stainless" for the tubing and muffler..... so what grade is it made from?

I'd love an exhaust that sounds as good as my old Corsa did on my '05. Deep and quiet at idle and under light throttle, louder at cold start and under heavy acceleration, but not obnoxious. I'm hoping the GM-Borla system is similar.

Borla is quiet. Get 14" magnaflow. IMO sounds very similar to Corsa, but better. Just my opinion.

I'd look at different exhausts but I don't want the chopper chase soundtrack. I also don't want to get rid of AFM because I've seen it work on the highway. Plus, I'm going to be leasing so I'm not sure how they'd take to a chopped up exhaust come return time.

I had the same experience with delays and canceled orders back in December and January. If you order the kit order the VT one as the ultra flo is about as hard to find as the tailpipe. Keep an eye on eBay though as they do pop up every once in a while. Edited by je1279

I had a Dynomax Race Bullet on my 07,11, and 14 silverado. They were all the 12" body length. This time, I'm wanting something quieter on my 2016 5.3 silverado. I'd like to have similar tone as race bullet (deep) just on quieter scale. What suggestions do you have?

I'd go either 14" dynomax ultra flo welded or 14" magnaflow (oval body). Either of those should give you the sound you are looking for.

Thanks. I'll look at both. Which size magnaflow oval (4x9, 5x8)? Is the 2.5" inlet/outlet recommend?

I went with an 18" 4x9 center/offset 3" on mine but I replaced the pipes with 3" dynomax pipes. If your just replacing the muffler you will probably need to take it to a shop as they will need to add some pipe due to the difference in length vs stock. I would recommend 3" since the stock pipe is 2.75" but which size oval would depend on which lines up better with the stock piping.

I would say mine sounds just like that now that it is broken in....

 

22" Maggie but the headers give it a nice raspy pop..

 

Left my gopro at home but il try to get some videos of how it sounds now.

 

 

I may want to step down to a 18"....i kinda miss being a little loud. Lol

I was able to find and order the Dynomax VT kit (38531). Swapping the muffler and using the 14" Magnaflow 4x9 center/offset. Sounds like we are doing the same thing just different length Magnaflow.

 

Should be at the doorstep by the time I get home today...

Enjoy and let us know how you like it. I disabled V4 after I installed mine (drove me nuts on the highway) but once I did that I loved it.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      Any joy with this truck seems to be short-lived.   The CEL for P0172 ("bank 1" too rich) is now "intermittent".   I'm not sure where to check, or re-check, and my energy to keep chasing problems with junk is wearing thin. The P0172 seems to set as I'm coming to a stop, completely off the throttle, when fully warm. At least, that's what it's done the 3? times it's set.   Everything appears normal on the scanner EXCEPT long term fuel trim. There's only one bank on this vehicle because it's an OBD 1.5 with only one upstream O2 sensor. At idle, it's around -16.4% and will dip to -18% occasionally at idle or off-throttle. LTFT approaches 0 when throttle is held at 2500rpm. Short term appears normal, much closer to zero all the time. The LTFT tells me the engine is running rich at idle but compensating at higher load. But, why?   The EVAP purge valve doesn't appear to be leaking/sucking fuel vapor continuously. Is it sticking just as I come to a stop and the engine is choking on fuel vapor and sets the P0172? But that doesn't explain the persistently negative LTFT. Disconnecting the purge valve doesn't seem to make any difference.   I suppose that leaves another dang issue with the fuel injector. A leaking fuel pressure regulator, a new leak in the spider, or a leaking fuel injector/poppet valve I didn't see, or a small crack in one of the spider legs.   The vacuum line leading to the fuel pressure regulator doesn't have raw fuel in it. It doesn't even smell like fuel when it's pulled off, not until you suck air through it, then you can tell it leads to a fuel component. I'd consider that normal? Nothing is signaling this is a FPR issue from the outside, at least.   The oil smells like fuel but it's not building volume. I've noticed most oil in most engines smells like fuel to some degree so it's hard to say if the smell is an issue or not. Or if the engine just still smells like fuel because the crankcase was full of it a few hundred miles ago. But it's been changed twice since that original issue of the leaking fuel line dumping fuel into the intake.   Patience is running very thin. Every win seems to be accompanied by two steps backwards, or another issue that leads to removing at least the top half of the intake manifold. Enough! LOL

      Tire pressure for 37s

      By Chuck FB · Posted

      First off you mentioned "Toyo Says" and then gave the pressures 45/50, was this some person at the tire shop that pulled those numbers out of his head ?   Now of course I can't know your exact axle weights front and rear, however I have much the same pickup as yourself other than not knowing your starting weight as per the pounds the truck rolled out of the factory at due to the options yours did or didn't come with or what you have added beyond the extra tire weight. The correct way to know 100% where a person is at is by weighing each axle with the typical weight the vehicle is driven with and that means taking into account passengers and making sure you figure in a full tank of fuel and a little grace for whatever you may put in the bed "groceries" !    I am looking at and not that it really matters as all the tire companies use the same charts anyway, but I am looking at the comprehensive Toyo tire chart in the section that your tire falls under and I know it sounds confusing but your tire is not an LT metric tire like your factory tire but instead because its a standard inch measured tire its under a different category called an LT floatation series tire. That makes a difference as LT metric tires they don't want to see run below 35 psi at highway speed where as with the LT floatation series it can be run down to 25 psi on the highway as long as the weight on the said size of tire is agreeable with or less than that minimum 25 psi. It blows many people away that how is this physically possible, an empty truck for one thing and larger tires with the same size wheel diameter have a lot more air volume so they can carry the same weight as the smaller tire with less air pressure.    So my truck, I have the stock 275/65R20 wheels and tires and I have a bit of weight in the box with a bak flip cover and a rubber bed mat and some tools and spare gas. The front of my gas truck weighs a bit more than some trucks of the similar spec due to double batteries and alternators. However with full fuel and just me in the truck I am weighted such that I can run 40 front and 35 rear and so that is what I have done since day one.    If I base your truck at or slightly below the weight of my truck, in theory with your tires going by the tire chart you might be right around a minimum of 30 pounds front and 25 pounds rear. Of course that would hit pretty much minimum cold inflation pressure one could run with that tire size and a near empty truck. If you have access to an accurate weigh scale to do individual front and rear axle weights I would suggest you do that and make sure your topped up with fuel and whatever else in the truck before you weigh it and then you will have a great starting point to work off of and figure out what your bare minimum pressures are you can safely run. If you do much in the way of hot weather high speed driving, bumping up a bit for a safety margin is never a bad idea but just depends on what type of driving you do. I will include the Toyo chart and the floatation series sizes start on page 31. Without a doubt at these pressures I am speculating at minimum wise for your truck, it would most certainly ride very different then it did when you were using 55 lb front and rear.     https://www.toyotires.com/media/pxcjubjs/application_of_load_inflation_tables_20200723.pdf

      Towing In Loose Gravel

      By rdonarski · Posted

      This landing is worse than most. Patchy blacktop with washouts, soft gravel/sand at bottom that washes out with every heavy rain. I tell everyone to put it in 4WD. A lot of them think they can pull out their trailer in 2WD. They end up digging a hole and then putting it in 4WD.  The lake is a pristine lake and has a lot of money on it. There are several wake boats and lot of large tritoons. The people with the money don't want it improved because they don't want more traffic.    Boat Landing 1.jfif Boat Landing 2.jfif Boat Landing 3.jfif

      Tire pressure for 37s

      By PBNB · Posted

      How wide are your rims?   Toyo specs 8.5-10.0-11.0 inches. My thought would be rim might be pulling the tire inwards creating a center that is more pronounced.    I also noticed that the spec sheet says max 65psi. So you could be right lowering the pressure to ~40 psi.
