Flowmaster

Flowmaster was founded in 1983 by Ray Flugger, who developed the brand’s distinctive delta chamber muffler design as a response to the lackluster sound of factory exhaust systems. The California company’s exhaust products became closely associated with the aggressive, low-frequency rumble that American performance enthusiasts recognize. For Jeep Wrangler owners, Flowmaster produces cat-back exhaust systems compatible with the 3.6L V6 Pentastar and 2.0L turbocharged engines found in JK and JL Wranglers. Their American Thunder and Outlaw series are among the more aggressive-sounding options, while the Super 40 series targets a moderate tone for owners who want a noticeable improvement without maximum volume. Flowmaster’s stainless steel exhaust systems are designed for direct fit on Wrangler platforms with no cutting or welding required. For Jeep owners who want to distinguish their Wrangler’s exhaust note from the factory output, Flowmaster is a well-established choice. Browse the full Flowmaster lineup at BlackDogMods.
