Gibson Exhaust 66204 Dual Sport Cat-Back Exhaust System - Stainless Steel

The Gibson 66204 Dual Sport Cat-Back Exhaust System is engineered for truck and SUV owners who want aggressive performance styling without compromising towing capability. The dual-exit design routes exhaust behind the rear tire, keeping the pipe clear of trailer hookups while delivering a bold, distinctive look on the street or the trail.

Built from 409L stainless steel heavy-duty tubing with mandrel bends throughout, this system minimizes exhaust restriction and maintains consistent flow from the catalytic converter back. Gibson's patented Superflow muffler design reduces turbulence at every transition point, unlocking power in the critical 2,000–4,000 RPM range where trucks and SUVs need it most. Dyno-verified testing demonstrates average gains of 10–15 horsepower and 15–20 lb-ft of torque.
