Headers, X-pipe, Air induction
Hello I am going to install long tube headers,X-pipe, straight pipes to the mufflers, Vortex ram air filter and a true complex Dyno test and tune this weekend on my 2002.
Has anyone done this and what kind of HP/holeshot should I expect.[/SIZE][/FONT][/COLOR]

I installed the American Racing 1-7/8" Long-tube headers, X-pipe, and 2 high-flow cats. At the same time, I installed a Vararam cold air intake.
I had a dyno run before the mods. I have a 99 with an A4 tranny. I clocked 275 HP bone stock.
After the mods, and without a tune, I clocked 307 HP.
So, I gained 32 HP with my bolt-ons.
I left my stock mufflers in place also...
