Overview
The Flowmaster American Thunder Cat-back Exhaust System transforms the exhaust note and flow of your compact truck with proven Flowmaster engineering. Designed for 1998-2011 Ford Ranger and 1998-2009 Mazda B3000/B4000 extended cab (2-door) models equipped with the 3.0L or 4.0L engine, this complete cat-back kit delivers a purposeful upgrade over the restrictive factory system. Whether you run a 2-wheel or 4-wheel drive truck, this system is built to fit both configurations.
At the heart of the system is the legendary Super 50 Series muffler, tuned to produce a moderate sound level that appeals to most enthusiast owners. It offers a deeper, more aggressive presence without the drone that can wear thin on daily drives and long highway hauls, striking the balance between street-friendly manners and true American Thunder character.
Key Benefits
Flow starts with a stainless steel mandrel-bent 2.5-inch flanged inlet pipe that feeds into a single-inlet, dual-outlet Super 50 Series muffler. From there, dual 2.5-inch mandrel-bent tailpipes route the exhaust out the back of the truck, capped off with a pair of large 3.00-inch polished 304 stainless steel tips for a finished, high-quality appearance that stands up to the elements.
Mandrel-bent tubing preserves a smooth, consistent inner diameter through every bend, helping exhaust gases move freely for improved flow compared to crimped factory piping. The dual-outlet layout not only looks the part but also complements the moderate, refined tone of the Super 50 muffler.
