Description

Speed Engineering 1-3/4" Long Tube Headers for 1999-2006 Silverado Sierra & Suv 25-1012

  • 1999-2006 GMC Truck & SUV (2wd & 4wd)
  • 2002-2006 Cadillac Truck & SUV (2wd & 4wd)
  • 2002-2006 Chevrolet Avalanche (2wd & 4wd)

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

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. The x-pipe kit can work on the 2 into 1 exhaust systems, but require fabrication for connection.

Note: Earlier 2500's might have fitment issues due to chassis being designed from previous years. Earlier years have the upper control arms mounted on top of the chassis, which would cause fitment issues.
