I came across these headers on eBay

I have the M112 E37 in my Crossfire. Was wondering if these might work with a
Bit of fabrication.

 

Clicked on the link and it wouldn't connect. If it's that way for everybody, you won't get many replies.

 

These ?
Mercedes Benz W220 S350 V6 Early M112 Engine Performance Exhaust Header Headers

 

I reposted the link. Yes Ala_Xfire those are the headers I'm talking about.

 

These are well made headers but they wont fit a Crossfire without a lot of modification. I had the V8 version of these (Top Speed) headers on my old ML55 AMG. They made an extra 45hp at midrange and about 13hp extra at the top end. I think it would cost more to purchase and modify them (as the rear angles are all wrong) then to buy a bolt on set from Needswings. The log style headers are a bit of a compromise but they fit well and make good power. I think they are definitely worthwhile.

Top Speed header

It seems the top Speed header would hug the block closer. I will have to look under my car to see what is in the way.
It may be worth having custom down pipes made an exhaust shop.
