525i 1990 - Need exhaust header

[Puma]

I am replacing the motor on my 525i. The new motor is from Bavarian Engine Exchange out of Sacramento. It is due to be shipped in about two weeks. It will have a polished head and hotter cam. I also ordered a clutch from same.

I have previously installed Dinan intake manifold and computer chip.

I am planning on replacing the exhaust system and headers. I have not been successful in finding a upgraded exhaust header.

Does anyone have an idea of where to find an exhaust header.

I guess this forum does not include the people who have a lead to find an manufacturer for a 525i exhaust header. ... or the standard exhaust manifold is so awesomely efficient that there is no need for the header. My next step is to check out that shop on Federal Blvd. here in Denver that makes custom headers.
