Gibson Single Series Exhaust Systems

Single Series Exhaust System by Gibson. Straight Out The Back Exit. Let the engine in your muscle car breathe and make it sound like a real muscle car with an American Muscle Car Stainless Steel Exhaust. The mandrel bent tubing and CFT Superflow muffler in this system will reduce restriction and increase exhaust flow for more power. The chambered and louvered design of the CFT Superflow muffler will deliver a powerful sounding exhaust tone.


  • CNC mandrel bent exhaust tubing
  • Improved performance
  • Includes CFT Superflow muffler
  • Chambered and louvered muffler design increases flow and delivers deep, powerful exhaust note
  • Dyno tuned for each application
  • Proudly made in the USA

The heart of the American Muscle Car system is the Gibson Superflow Muffler with Convergent Flow Technology (CFT). Gibson knows that increasing exhaust flow is critical for improving power, and that restriction is the biggest obstacle to increasing that flow. Gibson Superflow mufflers have some of the lowest restriction ratings of any muffler on the market.

Finally, all Gibson exhaust system components are joined with a “slip fit”, where an exhaust system component fits into the larger opening of the next downstream component. This method reduces the turbulence that is common with ‘ball-and-socket” or “flange-and-gasket” joints, which can cause power-robbing backpressure.

Gibson exhaust systems are manufactured in the USA.
