Gibson 12214 Cat-Back Single Exhaust System Aluminized Steel with Polished Stainless Tip

The Gibson 12214 Cat-Back Single Exhaust System is a bolt-on performance upgrade engineered to deliver meaningful gains in horsepower and torque. Dyno-tested to maximize output at low RPM (1,800–3,000 RPM), this single-side exhaust system exits behind the rear tire and is designed to reduce interior drone while producing a deep, aggressive exhaust tone outside the cab.

Key Features:

• Dyno-proven performance — Average gains of 10–15 horsepower and 15–20 lb-ft of torque, concentrated in the low-end power band
• SuperFlow baffled and chambered muffler — Fully welded construction with no internal packing or screening; nothing to blow out over time
• Mandrel-bent aluminized steel tubing — 2.25 in. diameter tubing maintains consistent exhaust flow through every bend, minimizing backpressure
• Slip-fit connection — Connects directly to the catalytic converter for a clean, leak-free fit
• Polished T304 stainless steel tip — 3 in. round slash-cut tip (2.25 in. inlet, 3 in. outlet, 8 in. length) with clamp-on attachment for a polished finishing touch
• Zinc-plated hardware and factory-style hangers — All necessary hardware included for a truly bolt-on installation; no welding or drilling required
• Minimal interior drone — Quieter in-cab experience compared to competing performance exhaust systems
