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.

Whether you are seeking a replacement Exhaust Manifold, increased fuel efficiency, or are looking for a extra “kick” on the highway with a Performance Exhaust Manifold, Highway and Heavy Parts has you covered. And, while some equate aftermarket parts with the term, “subpar”, HHP is here to set the record straight. HHP only offers premium Exhaust Manifolds with a industry leading 2 Year Warranty, all with savings up to 50% off OEM prices. How’s that for an aftermarket part?

Looking for proof? Let’s talk Exhaust Manifolds.

  • Let's face it, it's time to fortify your engine! Keep the power in horsepower with a new exhaust manifold by increasing your fuel mileage by .2-.3 per mpg and get 28-32 more horsepower
  • HHP knows durability is a necessity. Go another million miles with thicker exhaust flanges and center dividers to provide greater strength for your already hard working rig.
  • Not only will it be sculpted from one of the hardest, most heat tolerant high quality steels, a CeramiChrome coating is added to keep exhaust gas energy moving within your turbo. You can't beat that!
  • Make your diesel great again! This product is proudly made in the USA!
  • Leakage? Not here! To prevent any leakage, joints have 50% more surface contact and are pressed to fit to ensure everything will remain in place.
  • To top it off, each exhaust manifold is flow tested to make certain they flow 20 cubic feet of air per minute making it one of the most reliable products on the market.
  • Put the OE to shame! With HHP you will be saving money by paying a lower price, while still receiving equal or better quality compared to the OE!
  • Get back up and running in no time! All components of your exhaust manifold are built to OEM specifications. Thus ensuring they will correctly fit and work correctly in your C15.
