I'll be looking into the exhaust come spring/summer for my 3.6. So far, I haven't been able to find alot of video/sound clips of 3.6 exhausts on Chargers, so I started looking at 3.5s. I'm not sure how much different they will sound. The Pypes brand so far is my number one, and also the least expensive. Probably followed by the Flowmaster.
