Gibson 614001 Cat-Back Single Exhaust System Stainless Steel

The Gibson 614001 Cat-Back Single Exhaust System is a bolt-on performance exhaust upgrade crafted from T304 stainless steel with mandrel-bent tubing for consistent exhaust flow through every bend. Engineered and dyno-tested, this system delivers average gains of 5–10 horsepower with maximum torque and horsepower improvements concentrated in the low-end power band (1,800 to 3,000 RPM), making it an excellent choice for towing, daily driving, and general performance use. The single-exit configuration routes exhaust straight out the back for a clean, factory-plus appearance.

At the core of this system is the Gibson Superflow CFT (Convergent Flow Technology) Muffler — a baffled and chambered design with no internal packing material. This construction eliminates blowout risk over time while producing an aggressive exterior exhaust note with minimal interior drone for a comfortable cabin experience.
