Gibson 616610 Filter-Back Single Exhaust System Stainless Steel 4-Inch Tubing

The Gibson 616610 Filter-Back Single Exhaust System is a high-performance, single-exit exhaust system constructed from premium T304 stainless steel. Engineered for diesel truck applications, this filter-back system routes from the diesel particulate filter (DPF) back, replacing all downstream exhaust components for maximum flow and performance gains.

Dyno-tested to deliver maximum torque and horsepower at low RPM (1,800–3,000 RPM), this system is designed to improve acceleration, hill climbing, towing capability, and passing power. The baffled and chambered muffler design produces an aggressive exhaust note while keeping interior drone to a minimum.

Key Features:

• 4-inch stainless mandrel-bent tubing maintains consistent diameter through every bend for unrestricted exhaust flow
• 6-inch polished T304 stainless round tip (weld-on) with 4.00-inch inlet and 6.0-inch outlet for a bold, clean look
• Baffled and chambered muffler design — no internal packing, delivering an aggressive sound with minimal interior drone
• Exits behind the rear tire near the stock location for a clean, factory-correct appearance
• Includes all hardware and factory-style hangers for a straightforward bolt-on installation — no welding required
• Made in the USA and backed by a Lifetime Limited Warranty

This complete filter-back exhaust kit includes the muffler, all necessary tubing, hangers, and polished stainless tip. Installation requires no drilling or welding, making it an ideal upgrade for diesel truck owners seeking serious performance and a commanding exhaust tone.
