Legendary SLP exhaust note for your late model GM Truck.


Some great quality features of this exhaust are:

  • The entire exhaust system is made from high-quality stainless steel to prevent corrosion and enhance durability.
  • The 4.0" exhaust tip is constructed of high-quality double walled stainless steel that has been polished for superior corrosion resistance and durability, and is laser etched with the SLP logo.
  • The system has a sporty look with its side exit.
  • 3-inch diameter tubing is mandrel-bent to promote maximum flow throughout. Other companies tend to crimp-bend their exhaust, which can cause restrictions and inconsistent flow.
