just so you know there are no more HP gains in an X-Pipe over an H-Pipe and if you want pre muffler exhaust add dumps.

i cut the cats off my 1997 almost 2 years ago and the check engine light has been on ever since... but the added HP,torque, and maybe 1-2 mpg makes it worth it.. sounds like a beast with 2.5" tubing, true duals w/ flowmasters .... THE MONSTER SNARLS KEEP THE NEIGHBORS AWAKE!!!
