Are you willing to leave MPG on the table?

The Exhaust Manifold never gets the credit it deserves? that is, until it forms a crack. While it doesn't look like the Exhaust Manifold is an integral part of your engine, that leaking exhaust gas is just horsepower, torque, and ultimately, fuel efficiency vanishing into thin air.

HHP only offers premium Exhaust Manifolds with a industry leading 2-Year Parts and Labor Warranty, all with savings up to 50% off OEM prices.How?s that for an aftermarket part?
