After alot of cussing and praying, i finaly tracked down my idle, to dome dumbass little disk that wasnt seated just absolutely right, and my header works great. Even my auto can beat some cars now , Stock S4 5sp's better watch out.

 

nice! does the header really make that much of a difference?

 

i havent had it out on the highway yet, but even in an automatic it made it much faster, and the sound is drasticly different, sounds like a BMW M3 GT-r now.

 

Yes a header will do wonders. Glad to see people going with those, just make sure you got some quiet mufflers.

 

lol, i have stock cans, no presilencer, and 1 cat, this sob is loud as hell!!! YEAH!

 

i just got done driving it for a long drive, DAMN this thing is fast now, 60-80mph in like 3seconds

 

I got Racing Beat Header, Presilencer & Mufflers it throws flames and is loud as hell!
