Speed Engineering Silverado & Sierra longtube headers are made out of 304 stainless steel and offer great quality, performance, and affordability. Our Silverado & Sierra longtube headers are mandrel bent, tig welded, and feature natural stainless steel construction. All of our Silverado & Sierra longtube headers have been dyno proven. We stand behind our Silverado & Sierra longtube headers in saying you will not find a better fitting, quality built, budget header for your vehicle.

Features include:

  • Mandrel Bent Tubing
  • Race Version with "NO" Air & EGR Fittings
  • Full 2" Primaries
  • 3" Collector
  • Longtube Header Design
  • Silverado / Sierra / SUV LS Headers
  • Gains over 25+ rwhp
  • V8 Engines Only
  • 4.8L, 5.3L, 6.0L Engines
  • CNC Machined Flanges
  • Polished Stainless Steel
  • Standard Graphite Manifold Gaskets

Vehicle Applications:

  • 1999-2006 Chevrolet  SIlverado Truck & Tahoe SUV (2wd & 4wd)
  • 1999-2006 GMC Sierra Truck &  Yukon SUV (2wd & 4wd)
  • 2002-2006 Cadillac EXT Truck (2wd & 4wd)
  • 2002-2006 Cadillac Escalade SUV (2wd & 4wd)
  • 2002-2006 Chevrolet Avalanche (2wd & 4wd)

Revised Y-Pipe: Now works with 4L60E & 4L80E transmissions. Also allows more room for 4wd vehicles.

Note: If using a larger 4L80E transmission the bellhousing ears may need to be trimmed for proper clearance.

Note: Earlier 2500's might have fitment issues due to chassis being designed from previous years.

Note: Most 6.0 applications have a 2 into 1 exhaust system which our y pipe system will not work with. Double check your exhaust for confirmation of fitment with single exhaust. Our x pipe kit can work on the 2 into 1 exhaust systems, but require fabrication for connection.
