Gibson 9204 Cat-Back Dual Sport Exhaust System Aluminized Steel Dual Side Exit

The Gibson 9204 Dual Sport Cat-Back Exhaust System delivers a winning combination of real-world performance, aggressive sound, and bold dual-tip styling for trucks and SUVs. Constructed from aluminized steel with CNC mandrel-bent 2.5-inch tubing, this system is engineered to maximize exhaust flow while maintaining full pipe diameter through every bend — eliminating the power-robbing restrictions found in stock and lesser aftermarket systems.

Key Features:

• Dyno-proven performance gains of 10–15 horsepower and 15–20 lb-ft of torque, concentrated in the 1,800–3,000 RPM range where you need it most for daily driving and towing
• Gibson Superflow Muffler — baffled and chambered design with no internal packing; only 5% exhaust flow restriction versus 34%+ on a typical stock muffler
• Deep, aggressive exhaust tone with minimal interior drone or cabin noise
• Dual 3.5-inch polished T304 stainless steel slash-cut tips exit behind the rear tire, keeping the exhaust clear of tow trailers while adding bold dual-exhaust style
• Slip-fit component joints reduce turbulence and backpressure compared to ball-and-socket or flange-and-gasket connections
• Bolt-on installation — no welding required; includes zinc-plated factory-style hangers, clamps, and detailed instructions
• Designed and tested at Gibson's fully equipped R&D center using engine and chassis dynos, flow benches, and audio equipment
• Made in the USA by Gibson Performance Exhaust
• Backed by a Lifetime Limited Warranty against defects in materials and workmanship
