Hello

I have some Headers in my Runner. I have heard that the original HP Exhaust Manifolds have the performance close to my headers... is there a truth about that, or is it just a story? i am thinking to come close to something like F.A.S.T Cars, original looking with performance... with exhaust manifolds!



no way. The FAST guys sink $$$ into their mani's and if they could they'd all run headers. Not saying you can't run fast with mani's but you'll pretty much always run better with headers. Especially on anything over stock build. I'd leave them on unless you are planning on entering a restrictive class like FAST or factory stock.
