Product Details

The Hooker 7901HKR Competition Long Tube Headers deliver maximum exhaust flow and performance gains for serious enthusiasts. These painted headers feature mandrel-bent tubing that eliminates restrictive crimps and ensures smooth, unrestricted exhaust flow from the engine to the collector.

Key Features:

  • Lightweight 16-gauge steel tubing provides excellent durability without excess weight
  • Tuned-length primary tubes optimized for maximum horsepower and torque gains
  • Precision 5/16-inch machined flanges create a leak-free seal at the cylinder head
  • Long transition collectors reduce backpressure for improved exhaust scavenging
  • High-quality welds throughout ensure long-lasting performance
  • Compatible with factory power steering and power brake systems
  • Complete hardware kit included for straightforward installation

Engineered for a trouble-free fit, these Competition headers are designed to deliver noticeable performance improvements while maintaining compatibility with essential factory accessories. The painted finish provides corrosion resistance for extended service life.

Fast and easy

Autoplicity was great, I ordered my springs late Monday night and I received a shipment order confirmation number early Wednesday. So basically 1 business day and my order was out the door, pretty impressive. Can't wait 'till it gets here! Thanks Autoplicity!

Best price online for the programmer I ordered. Fast and reasonable shipping costs.

Best price I could find after hours of searching, I recommend 100%!!!

They had the best price on a hitch I was looking for and the shipping was fast also. The hitch was shipped bare except for taping the box of bolts to it thus leaving the hitch open and chipping the paint/powdercoating in quite a few places which I had to touch up before installing.
