sounds ok at best, but i would never buy any ebay parts unless they were dyno proven..

 

According to a few ppl on e46fanatics they produce 15-20hp and they are pretty much an exact replica of the Supersprint headers.

 

To me eisenmann race is one of the best sounding exhausts for BMWs. Here's one of the new M3

sounds just the way I like it for a 6 cylinder engine

 

I apologize for my ignorance but what are ebay parts?

They are knock-offs of named products?

Ebay headers are reproductions of more expensive headers like supersprint and eisenmann.. $175 compared to $3500..ppl say they are just as good

 

I've installed them before.

Fitment is garbage from what I'm use to. Bank 2 O2 sensor was rubbing on the bellhousing of the trans. Would of had to been relocated/welded to fix it.

For the price they obviously can't be beat. But CSL headers are the next best bet, used they can be had for not much more.
