Reference Information

2004-08 F150 Triton 5.4L 2WD/ 4WD Catback True Dual Exhaust with chambered turbo mufflers, clamps and hangers

Stainless Works CNC mandrel-bent exhaust systems are the simply the best for improving your vehicle's performance, sound, and mileage. Made of high-grade 304 stainless steel, they offer an array of options to unleash more torque and horsepower while delivering the sound your vehicle has been lacking. Most are designed to use factory hangers.

Stainless Works not only offers their Factory Connect option that mates to a factory connection point, but also Performance Connect options for many models. Performance Connect gains more performance than factory connection points allow, and they require the installation of Stainless Works headers (sold separately) to gain the full performance benefit.

Stainless Works also builds their mufflers entirely of stainless steel. They will never "burn in," "blow out," or change their tone—ever. Choose from a selection of universal or application-specific muffler designs, including turbo chambered (loud), chambered round (louder—can be reversed for an even more aggressive sound), and turbo S-tube (loudest—may be too aggressive for a daily driver).

Additional features of Stainless Works CNC mandrel-bent exhaust systems include:
• 304 stainless will never red-rust like cheaper 409 stainless
• TIG-welded for strength
• Durable 3/8 in. thick flanges
• Mandrel-bent (no buckling) for optimal flow
• Variety of tip options (varies by application)
• Truck exhausts available with three exit locations: behind the passenger tire; under the rear bumper (one on each side); and in front of the passenger tire
• Install-Ready; all systems come with all necessary parts to make installation as smooth as possible
