Cat-Back Single Exhaust System Aluminized GIB315547

A quality exhaust system is foundational to any performance build—it reduces back-pressure, improves throttle response, and unlocks horsepower your engine is already capable of producing. This cat-back design gives you a straightforward bolt-on upgrade without custom fabrication, while the 4-inch and 5-inch diameter components optimize flow for GM full-size trucks. The aluminized steel construction resists corrosion in harsh conditions while maintaining durability through years of daily driving and weekend abuse.
