I hear a lot about the Harvey headers a lot of people seem to fit them.Are there any gains from having them or is it just a name.Also is the up pipe separate from the headers or is it all one system.

Harvey (rip) new his stuff when it comes to headers and upipes .

I've heard nothing but positive feedback saying that they lessen spool time .

Best get the headers and a upipe that suits your needs .

As they'll know what dia upipe will suit your turbo best

Are we talking big money here

Alyn at AS performance has been selling the stuff harvey's developed, well worth the money imo.

 

Spoke to harvey many times on the phone and met him a couple of times. Such a loss to the subaru world :( RIP
