  • Mandrel-bent tubes provide consistent tubing diameters for smooth flow and increased exhaust velocity
  • Heavy duty 16-gauge tubing for increased strength and durability
  • Smooth transition, 1-5/8” diameter primary tubes are used for increased exhaust flow increasing performance and improving throttle response
  • OE style 2-1/2” ball and socket collector connects to factory exhaust head pipe with no cutting or welding
  • TIG-welded, machined 3/8” header flange for a leak-free seal and maximum strength


FlowTech's emissions-friendly headers are just the ticket for those who want the best of both worlds - top performance and a clean machine. All shorty smog headers bolt on quickly and easily to the factory exhaust system, retaining all stock emissions equipment, and offering maximum horsepower gains plus increased efficiency.

Fit my truck perfectly. They create a ticking type of sound but that’s just the difference between the factory manifold and the tubes style. I believe it’s called header tick. My recommendation is to use factory style gaskets and not the perforated gaskets they give you. I got a set of Mahle gaskets.Overall, I’m happy with them.

Been looking to get new headers to increase sound and power, also been comparing reviews seen this one didn’t have a review would love to be the first to give the item a true review, but not sure if the item is worth the price.
