Cat-Back Exhaust System

The Gibson Exhaust Cat-Back Exhaust System (SKU: GIB70-0041) is engineered for enthusiasts and mechanics who demand measurable gains in engine efficiency and sound quality without compromising reliability. A cat-back exhaust begins downstream of the catalytic converter, meaning it preserves emissions compliance while unlocking horsepower and torque that stock systems leave on the table. This system is ideal for daily drivers and weekend warriors alike who want real performance without full exhaust system complexity or warranty concerns.

Gibson Exhaust manufactures this cat-back assembly using durable mandrel-bent tubing and precision welding techniques that minimize turbulence and backpressure throughout the exhaust path. The design focuses on smooth transitions and optimized diameter piping to allow exhaust gases to exit with minimal restriction, which directly improves cylinder scavenging and combustion efficiency. Weighing 46 lbs and engineered for durability, this system resists corrosion and thermal stress while delivering the acoustic character that separates a performance exhaust from a muffler swap.

Installation of the Gibson Exhaust Cat-Back Exhaust System typically requires removal of the factory muffler assembly and rear piping, then bolting the new system to your vehicle's existing midpipe connection at the catalytic converter outlet. This bolt-on approach means no welding, no hangers to fabricate, and no cutting—making it accessible for mechanics with basic hand tools and moderate suspension or lift experience. Verify your specific vehicle application before purchase, as Gibson manufactures application-specific kits; the modular design (15 x 12.5 x 57.25 in packaged) ships efficiently and fits standard engine bays without major modification.
