...and which is best? I just want to know what everyone out there is using, since I'm planning on buying one soon. Thanks for the help.

headers dont do much for our cars, if you want looks then get a greddy header or bosal headder, if you want the power/less restriction your better off porting out your stock exhaust manifold, it will yield better power gains.

Thanks for the info. I thought that headers derived their power increases from their equal-length runners, which smooth out the airflow exhaust pulses. I can see a ported exhaust manifold flowing better, but not doing much for tuning exhaust pulses... since headers don't help much, I guess our stock manifold is already pretty close to the "optimum" length?

P.S. - Can anyone see my signature/avatar? I'm not sure if my host allows remote linking. Thanks again guys!

ive got a greddy header and frankly...it didnt really do much..about the only thing i have done that works is the AEM coldair...the Apexi N1 catback added a negligable amount too.

yea, I agree with mcgyvr on this one. header is a waste of money on our cars. only good thing about is it is definately better looking then our stockers (don't take off your exhaust manifold shield). and no your sig/avatar are not showing

I third that ^^^^^^^^^^^^^

way too much money for the negligible gain
