Product Details

The Stainless Works CT6773CS is a complete cat-back exhaust system engineered for 1967-1987 Chevrolet and GMC trucks with small block or big block engines. This performance exhaust system delivers enhanced flow, aggressive sound, and long-lasting durability for classic truck enthusiasts.

Key Features:

  • CNC mandrel-bent 3-inch stainless steel tubing for optimal exhaust flow and maximum power gains
  • Premium 304 stainless steel construction provides superior corrosion resistance and longevity
  • Dual chambered round mufflers produce an aggressive, deep exhaust tone without drone
  • Tailpipes exit in stock location behind rear tires for clean, factory-style appearance
  • Designed to work with Stainless Works headers and most aftermarket header systems
  • Precision-engineered fit for straightforward installation
  • Proudly made in the USA with lifetime warranty coverage

This cat-back system combines performance gains with classic styling, making it an ideal upgrade for restomods and classic truck builds. The mandrel-bent construction eliminates restrictive crush bends found in factory exhausts, while the chambered muffler design balances sound quality with flow efficiency.
