Product Details

The Gibson 65652 Cat-Back Dual Extreme is a performance exhaust system built for truck owners who demand aggressive sound, bold looks, and real power gains. Constructed from stainless steel mandrel-bent tubing, this dual cat-back system delivers a deep, powerful exhaust tone with dyno-tested performance gains averaging 15–20 horsepower. The system reduces backpressure to increase torque and improve overall engine efficiency.

Exits are positioned behind each rear tire at an aggressive angle, giving your truck a commanding presence both on the street and at the track. The baffled and chambered muffler design produces an assertive sound character with minimal interior drone — all without internal packing that can degrade over time.
