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.
