Hey I have a 2003 b6 a4 and am looking for horsepower and need sugestions on upgrades?????? what worked and what was a waste of time? I installed a blow off not knowing it was a recirc and it was pointless... I have an ARE cool air intake and apr reflash and need ideas where to go from there? I am planing on a catless down pipe and am wondering if anyone has done that in here ; and what kind of power gain they have seen? Also am debating wether or not to rebuild the engine or if it will be worth it... any advice would be GREAT..... please help

Oh and my name is andrew

 

this has been discussed a million times, and the b5 section has a stickie, i would assume the b6 section does to....on how to make your car faster


intake is pretty pointless, just more for sound, testpipe helps exhaust breath so yes there is some gain, how much i doubt anyone has truly dyno'ed to find out, if coupled with a full exhaust system you will really notice it.... but if you want big gains, you need to change turbos
