Gibson Performance Exhaust 619001 Axle Back Dual Exhaust System Stainless Steel

The Gibson Performance Exhaust 619001 is a stainless steel axle-back dual exhaust system engineered to deliver aggressive sound and real performance gains. Constructed with 2.50-inch 409 stainless mandrel-bent tubing, this system maintains consistent exhaust flow through every bend for improved efficiency and output. Dyno-tested to produce maximum torque and horsepower gains in the low-end RPM range (1,800–3,000 RPM), this system delivers an average increase of 10–15 horsepower and 15–20 lb-ft of torque.

At the heart of the system is Gibson's baffled and chambered SuperFlow muffler, which uses resonance chambers, directional louvered tuning ports, and angular induction to draw exhaust gases in and expel them at higher velocity. The result is a deep, aggressive exhaust rumble with minimal interior drone — all sound, no headache. Exhaust exits straight out the back of the vehicle for a clean, factory-inspired look with serious aftermarket attitude.
