Hi,



Regarding this 2wd exhaust manifold, the ebay_seller said :

"This is a must for big BHP Cosworths. Will help Turbos to spool up quicker and more. When I bought it I was told it would give15 - 20 BHP.
Please note to fit this manifold you will require modifications. Due to the fact I have not fitted this manifold I do not know if they are minor or major."

Where is the problem ? I have not confidence.
Thanks for all info.

Regards.

Claude
