Gibson Performance Exhaust 617007 Muscle Car Cat-Back Dual Exhaust System 409 Stainless Steel

The Gibson Performance Exhaust 617007 is a cat-back dual exhaust system engineered for the muscle car enthusiast who demands both aggressive sound and measurable performance gains. Constructed from durable 409 stainless steel with mandrel-bent tubing, this system reduces backpressure for improved exhaust flow from idle through the power band.

At the heart of this system is Gibson's signature SuperFlow™ Muffler featuring Convergent Flow Technology (CFT) — a baffled and chambered design with no internal packing to blow out or deteriorate. Directional louvered tuning ports and angular induction work together to draw exhaust gases in and expel them at higher velocity, delivering optimum low- and mid-range power with a deep, aggressive exhaust tone and minimal interior drone.
