Hello, how are you, using this product, I mean, wraping my RX7 Header or manifold, and exhaust pipe I can Gain more Power? Thank you

 

I doubt you'll notice any real power gain. The advantage of wrapping the downpipe is to reduce underhood heat, which can damage plastic parts and vacuum hoses. It may also quiet your exhaust a bit. I wrapped back to my catalytic converter to help a little with radiant heat to the transmission too.

 

it should def let your fd last longer...heat is one of the biggest problems with rx7's. and protecting vac hoses is a huge deal. its a big pain replacing them
