Evening all just wondering where the best place to get headers from is and what is the best make to go for and will also take up 400 bhp comfortably? (also want to keep the burble)

 

We carry the genuine GTSPEC headers, there are some out there marketing themselves as GT Spec such as Kakumei but they are different so do not be mislead.
LP, RCMS and Tracktive also have offerings that are of the same design and as good quality as the genuine GTSPEC so shop around

 

If you live in the UK ... they are called MANIFOLDS!!!

A HEADER is what Peter Crouch at Liverpool does each Saturday ....
