need some input. looking to upgrade to headers that attach to each exhaust port instead of two sets of three ports. car is lowered by lowering springs, not entirely sure how much. thanks.

i did use google, and i found a few different ones. right now i have 2 sets of three and i couldn't find any. but then again i didnt look hard. would each individual pipe perform better than the 2 sets? i read on bimmer forums that it allows more exhaust to flow through because the ports arent all connected to each other. like i said i just wanted some input/ideas. not entirely sure im going to do this yet. but my headers aren't so great.
/e forgot to mention they're all one piece. not separate pipes that come together. all pushing through the same tubes.

Luckily for you, I'm helping one of my closest friends build his 325is.

The header your looking for is this one. We've done the research. This is definitely what you want, if you care about your exhaust.

Ireland Engineering is the tits when it comes to e30 stuff.
