I drive a 2000 max 5-speed. I just had my Cattman y-pipe, randomtech hi flow cat, and full Cattman cat-back exhaust installed. All that I can say is: WOW! what a difference. ( I also have a PR cold air intake, but thats been in for a while now) The power difference is VERY noticable. Right now I have 215 yokahamas as tires and I can bearly keep traction all the way through first and can very easily spin shifting into second. Don't know if I can chirp going into third, haven't tried yet. and the sound, oohh the sound. Deep at low rpms. and thru the rpms its throaty, but never high pitched. I'm very satified w/the sound. Not ricey at all, which is what I was afraid of. The cattman b-pipe has a huge resonator that makes deep, throaty sound I'm guessing. And it's not just the power that I'm thrilled with. Before, if I was accelerating in first or second then let off without pushing in the clutch, it would lurch bad, like my gas pedal was just an on/off switch. now, when I let off of the gas it just coasts (and makes a small gurgling sound ). sooo much more smooth. anyway, just thought that I would share my experience w/everyone. When I was researching a full exhaust, I was interested in Cattman from the start b/c of good quality, but I could never find anyone with the entire setup. So I made a blind leap... and man, it was better than I expected. anyway, sorry so long guys.
