First post, here goes! I just put some money into my 04 Yukon xl Denali 6.0, suspension, tires, and a K&n intake 234,000 miles. Now I’d like to do the exhaust, was trying to make a Flowmaster 50 deltaflow work but couldnt. My truck has a strange muffler setup stock where it’s a dual in with the ins at different heights and dual out to a y to a single. The best option I see so far is the Gibson 615534 which is stainless and basically a cat back. I’ve never heard a Gibson in person – my main question is if anybody has one, does it drone much?
