Headers for '05 3.0 (M54)?

CFoote · 01-02-2011, 06:50 PM

Does anyone make a set of headers that fit the M54 in the Z4 that are of decent quality?

Thinking a nice cam (Schrick?) / header combo would give a nice 25hp.

supersprint and active autowerke are going to be the easiest to get ahold of.

From what I have researched, the manifolds in our car come equipped with the cat. converters built in, which makes adding headers rather difficult in regards to keep emissions equipment. When I mean rather difficult, you won't pass a smog inspection if your state has one.

Back to looking at superchargers....
