The Gibson Swept Side Cat-Back Exhaust System is designed and built to make horsepower and torque for real world driving conditions. Dyno results show that this system makes maximum horsepower and torque at 1800-3000 rpm where you can feel it during every day driving and where you need it when doing things like towing a trailer. And along with that increased power and improved performance you get better fuel economy and a nice deep aggressive exhaust tone.

Gibson designed this exhaust system at their fully equipped research and development center using engine and chassis dynos flow benches and audio testing equipment. To make useable real world power Gibson equips this system with a Suspended Flow Technology (SFT) design muffler and mandrel bent tubing. The all-welded construction SFT design muffler is baffled and chambered for better volume efficiency with unrestricted flow. It's so efficient it has only 5% exhaust flow restriction as opposed to the 34% or more restriction in a typical stock muffler and the 10-20% restriction that exists with some aftermarket mufflers. And the increased flow and great sound is achieved without using any muffler packing so there's no packing to blow out. Your exhaust flow and sound will remain consistent throughout the life of the muffler.
