Direct Fit Muffler Systems
Flowmaster Direct Fit Mufflers can be found in three different muffler configurations ranging from mild to wild.

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.
