Looking for headers!!!!
Well I hear the gains are impressive, and they make your car sound louder. Honestly after I got my intake, exhaust, and resonators taken off the sound I have acheived. Alittle or alot more defintely cant hurt though. Based on performance gains I'm still not where I wanna be. Who knows If I ever will like the next guy, but I figure this is a big step in the right direction. So any help based on prices for my 2003 325i and of course brands would be greatly appreciated?????? Also what website to go to because I've been to a couple and they never seem to have my year. At the moment I know of supersprint and technik, but I couldnt find prices for my year and model.
