One of my friends on LS1.com was telling me the other day about a "dynomouth" exhaust that some of the guys were putting on their ls1's. What it basically consists of is a dynomax bullet muffler located in the I-Pipe and just running two tailpipes out from where the stock muffler would be. I'm thinking of going with the 3" I-pipe and a 3" in/out dynomax bullet in the middle of the I-pipe then running out the two tailpipes in the stock locations from the end of my I-pipe. Oh yeah, I also have 3.5" X 18" long slant cut chrome tips to go on it. I'm thinking this will sound and look pretty nasty. Anybody else done anything like this? How does/will it sound? How bout the flow? Gotta be better than the crossflow muffler, right?
