mia2005

Whats up guys. I picked up a 2005 M6 about a month ago and think I have narrowed it down to getting a kooks muffler delete and h pipe. I dropped the stocks earlier today as a test for the deletes and liked the results.Does anyone have this setup that they might be able to post a video of? I'm unsure of the effect the h pipe will have on the popping and in general as I've heard mixed things that it increases/decreases it. Also I've heard mixed things on issues with back pressure leading to potential valve damage and decreased performance. I'm not sure if those who said the issues concerning backpressure are misguided or correct. Any insight is really appreciated and please excuse my lack of knowledge.
