My mods are: intake, 3" downpipe, 3" cat-back exhaust with stock cat, and mbc at 8 psi. I raced a v6 mustang from a 40 roll and beat him by 2 cars both times. He said he only had exhaust but i don't believe that because i should have beat him worse. And the audi a4 was a 1999 and making 240 whp and 320 tq. I new i was goin to lose but i just wanted to do it for fun. From a 40 roll he pulled 3 cars on me and then from a 60 roll he pulled 2 cars. I was pretty happy with the races.
