Flowmaster Axle-Back Exhaust Systems

- Axle-Back System Types
Flowmaster Axle-Back's can be found in four different muffler configurations ranging from mild to wild. If you're looking for an aggressive tone the Outlaw Series and American Thunder are for you. If you're looking for more of a moderate exhaust tone but still packs a big punch check out the FlowFX or Force II systems. - Finish & Exhaust Tip Options
Most Flowmaster systems are made from a durable 409S stainless steel tubing and can be found paired with black, black chrome and/or polished stainless exhaust tips to give your ride a custom look. Depending on your vehicle we have systems that are single exit, turndown exit, dual exit or dual quad tip exit. - Materials
Flowmaster uses many different materials when it comes to building completely custom systems to bolt directly on to your vehicle. Most of our kits are made from an extremely durable 409S stainless steel with some of our older systems being made from the tested and reliable aluminized steel. Flowmaster's Signature Series is made from top of the line 304 Stainless Steel. - Vehicle Support
Be it a domestic or import truck, SUV, off-road warrior, daily driver, muscle car, euro-spec cruiser, or sportcompact vehicle, Flowmaster technicians personally hand-select the right muffler, tubing size, resonator, and tip to make the process easy for you. - Installation
Flowmaster Axle-Back's bolt on using simple hand tools and re-use all of the factory mounting locations and hangers. For tips and tricks, check our detailed installation videos!
