Built for the 1992-1994 Chevrolet C3500 with the 6.5L diesel, this Gibson cat-back system uses 3in mandrel-bent stainless tubing and a single side exit behind the rear tire. Gibson rates its single side exhaust for low-end torque (1800 to 3000 RPM) with average gains of 10-15 horsepower and 15-20 lb-ft, and says it stays quieter in the cab than other performance exhausts.

Key Features

  • 3in mandrel-bent stainless tubing
  • Baffled and chambered muffler with no internal packing, for minimal interior drone
  • Muffler: 8in round body, 3in center inlet, 3in center outlet, 24in long
  • Tip: 3.5in polished T304 stainless round slash-cut tip, clamp-on
  • Tip size: inlet 3in, outlet 3.5in, 12in long
  • Exits behind the rear tire
  • Bolt-on installation, no welding required
