ARH + Corsa Sport is too much! Swap for Touring?

I have a 2017 Sierra Denali 6.2L and threw on a Magnuson TVS1900 supercharger.  I originally ran this with just the Corsa Sport exhaust and it sounded great and the sound level was reasonable.  It was loud when I hammered on it, not bad when I was cruising.  But then I installed American Racing off-road headers and it is ridiculous.  It sounds great, but really its just too loud for daily driving use.  I think if I swap to the Corsa Touring muffler it would be quiet enough but still sound good and would keep the throaty sound you get from the headers.  But I can't find a touring muffler for sale without having to buy the whole exhaust.  

 

Does anyone know how I can get just the touring muffler?  Or any other suggestions to tame this beast down a bit?  I really don't want to cut up my beautiful Corsa exhaust so I'm looking for a solution that I can bolt in without cutting any part of the original Corsa system.

Dynomax makes a stainless intermediate pipe for the 5.3 not sure about the 6.2. You could buy an intermediate pipe, cut it too length and put a resonator in front of the Corsa muffler.

No, you cant just buy a touring muffler. If you want it quieter buy the gm performance exhaust (that is the touring muffler). Or you can had a resonator before the muffler, which essentially makes it a touring muffler (according to Corsa). But, if your a crew cab short box there's too many bends to just put one in, you'd have to get an exhaust shop to make you modified one. 

 

When it comes down to it, you either have to cut it up (add resonators/mufflers) or buy a new cat back.

Thanks guys!  I do have a crew cab short box...so I agree there are too many bends to fit a resonator in there.  I did think about welding the stock resonator back in place, but I didn't want to cut that section of the corsa to do it and later find out it didn't really get me to the sound I wanted.

Maybe you could take the tip off and temporarily attach the resonator in its place? Wont be exactly the same but might give you an idea on sound.

 

*Edit*

 

I'm not sure about your stock exhaust but mine goes from 3 1/2 to 3. I bought a race muffler (borla 40004s) for this same purpose. Overall its 13 inches, muffler body is 8x5 inches and looks like it will just fit in that same location on the corsa. No idea what it sounds like yet, or if it will make that much of a difference.

id look into one of these... Vibrant Ultra Quiet Resonator

 

these are also popular to add to system.... venom, carven, aero muffler

they are all fairly small, should be easy to add before/after your muffler

I have a crew cab short box and was able to fit a resonator before the muffler.

Do you have a picture?

 

I know on my 6.2 I cant picture how it would work because the pipe starts to bend right off the muffler. Maybe your 5.3 has a straight section.

Wish that placement was an option for those running corsa. The muffler is much longer. Probably going to have to put it after the muffler where the stock resonator is and weld it.

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

      By richard wysong · Posted

      I had an 88 K1500 with a 5.7 that had those symptoms, I know totally different, it ended up being the ECM. Once you get the fuel system fixed if it still runs lousy you may want to investigate that. it didn't set any codes, stalled ,ran rough at times etc

      Trading 7.3 (Godzilla) for G.M.C gas

      Congratulations Isttype, on your gmc. Really like my 2024 2500hd sle doublecab now with 85,500 miles.  I checked the oil today at 4800 miles since last oil change and barely reading on the stick.  I don't care if GM says it's Acceptable adding a quart every 2000 miles because that is 100% BS, It is not a 1966 Harley Shovelhead! Sounds like it's setting up a future failure like I had with my 1500 6.2l. Other than oil consumption problems, I really like the 6.6l gas and 10 speed is really nice.  Towed a light 4000 pound trailer last week and averaged 14 mpg.  I was pretty impressive that a 7300 pound gas truck did 14mpg towing, Later-

      Long Term Cold Cycle Limited Testing   Back to the 1990's and XOM's million mile test. Since then there have been others and there will be more. Schaeffer's, AMSOIL to name two. Of these Schaeffer's is the stand alone which I will explain in a bit later.    http://papers.sae.org/600190/:   http://papers.sae.org/850215/:   Up to 75% of  engine wear occurs on cold starts. These two links (above) provide the technical reasons for engine wear. In a nut shell, and by a large margin, cylinder wear is what takes out most motors and even with a pre-oiling system that part of the engine is dry enough on cold starts and cold warm up to pierce Stribeck.   So when you put a motor, or a car, on a dyno for a million miles stopping only for oil changes, (yes fuel is uninterrupted) or break down maintenance, you are depriving the test of the most important part of it's wear cycle. Yes a million is then a pretty easy walk even for a mineral oil under those conditions.    How about cleanliness during the long test cycles? Same thing. Varnishes that stick rings and insulate parts are laid down by repetitive 'heat cycles'. It's the cool down the precipitates the varnishes. These long runs also hinder acidic attack caused by cold start richness and less than optimal cold start ring sealing. They hinder water formation and enhance breathing of the crankcase; the petri dish of acid formation, the first step in sludge formation, amalgamation and precipitation. These motors are also monitored and controlled for water and oil temperatures to within the "normal operating range".      https://www.swri.org/sites/default/files/sequence-iiih-test.pdf Note the test sequence in some boutique oils literature for testing, API IIIH, is not the standard used for the ILSAC G7 testing. Does that mean it is irrelevant? No, not as used. As used as a 'visual guide' it makes it's point. The G7 weighted piston deposit minimum is lower.      Back to Schaeffer's. That was a cyclical test of an engine in fleet service and not a dyno mule and if you saw the video it was not mirror clean but wear was low.    There are oils like BioSyn and other 'Renewable" source oils that taught cleanliness and have proven themselves in fleet testing. Havoline an other example.    The newest ILSAC G-7 test prioritize cleanliness, LSPI mitigation and fuel economy OVER WEAR. In comparison Porsche C30 Specification Verses ILSAC G-7 Specification below:      Some will balk that this graph isn't apples to apples and I will challenge that in that this graph represent the SPECIFICATION and not the any One Oil Performance.   It is absolutely possible to minimize wear, maximize cleanliness and mitigate LSPI etc., It just isn't cheap and currently I see none that are not walking toward profit over performance.

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By asilverblazer · Posted

      I don't think you will need a split, separate product, etc., the OBD port should be able to deliver everything you need. Since your device would be plugged into it all the time, it wouldn't miss anything.    Hardware in this case will be the easiest part of your project - ELM 327 devices will already deliver all the data you need. Reporting/software is where your advantage/marketability is.
