Product Details

The Gibson Exhaust GP500S Performance Header is engineered to maximize your engine's efficiency by improving exhaust flow and reducing backpressure. This stainless steel header is dyno-tuned to deliver measurable gains in horsepower and torque at low and mid-range RPM, where you need it most during everyday driving and highway speeds.

Key Features:

  • Stainless steel construction for superior corrosion resistance and durability
  • Dyno-tuned design optimizes power delivery at low and mid-range RPM
  • Improves engine breathing and reduces operating temperatures
  • Direct-fit replacement for factory manifolds using stock crossover pipe
  • 3/8" heavy-duty laser-cut port flanges prevent warping and leaking
  • OEM-style connections for bolt-on installation—no welding required
  • Suitable for stock, lowered, and raised vehicles
  • 50-state street legal—meets EPA and CARB emissions requirements
  • Premium gaskets and all necessary hardware included

This performance header is designed to work with your vehicle's existing emissions system, ensuring it will not affect your factory warranty. Gibson backs this header with a lifetime limited warranty, giving you confidence in your investment.

Order 12486. Item was simple to find and the website made it very easy to navigate. I appreciated the ability to pay with paypal and email notifications gave me confidence that everything was taken care of properly.

Bought a Husky gearbox for my Silverado, great price and a great product. Install was simple and the fit was perfect. Gone are the days of opening the rear door and all the items under the seat sliding out. Great for my hitch, tow straps, jumper cables and other miscellaneous must haves in a truck. Great seller the price was the best on the net even with shipping. Item arrived quick and in perfect shape. Thanks!!

Just received my order! I placed the order Sunday night and received it on Tuesday, super fast shipping! The SS vent caps look great and arrived in perfect condition. Thanks!

Loved ordering from Autoplicity. Was the cheapest price around and best quality. Will be ordering again in the near future.

Return customer with a few more future purchases in mind...best price plus quick shipping means these guys are just that good!

Very smooth ordering and processing. Great communications.
