This kit replaces the factory muffler with a straight-through 3-inch T409 stainless steel mandrel-bent bypass pipe, delivering a noticeable sound upgrade and improved exhaust flow without going over the top. The result is an enhanced, moderate exhaust tone that lets your truck be heard while remaining refined for daily driving. Finished with a sleek 4-inch OD polished exhaust tip for a bold, performance-inspired look.

Note on Emissions & Street Legality: A muffler bypass replaces the factory muffler with a straight-through pipe. Muffler delete/bypass modifications may not be legal for street use in all jurisdictions — verify local noise and emissions regulations before purchasing and installing this kit.

Key Features

• Deeper, Enhanced Exhaust Tone: Replacing the factory muffler with a straight-through bypass pipe delivers a noticeably deeper, more aggressive exhaust tone from the 4.3L V6 and 5.3L V8 — a meaningful sound upgrade that lets your truck be heard while remaining moderate enough for daily driving
• T409 Stainless Steel – Rust & Corrosion Resistant: Constructed from T409 stainless steel — an excellent rust and corrosion resistant material for long-term durability in all weather conditions. T409 is MBRP's standard stainless grade for truck exhaust applications
