Direct Fit

Direct Fit Muffler Systems
Flowmaster Direct Fit Mufflers can be found in three 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 systems.
Simple Installation
Just a few bolts with hand tools in your driveway and you're turning heads! Simply drop out the factory muffler, bolt your new Flowmaster Direct Fit Muffler up using all of the factory hangers and you're good to go. This is a fantastic way to get the classic Flowmaster rumble without breaking the bank or requiring a lot of work.
Vehicle Support
Flowmaster has Direct Fit Muffler support for Dodge Ram, Ford F-150, Ford Raptor, GM Silverado and Sierra.
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.
