As Flowmaster is known for, this muffler has the signature deep, throaty sound that sets it off from the competition. I had it installed on a '95 Dodge Ram and it was perfect. The workmanship was high quality and I think it will outlast the truck.

I ordered it and got it two days later...took the saw zaw to my factory 2015 tundra SR 4x4 5.7..exhaust right before the muffler. Slid this on the two pipes and centered them on the pipes with temp spacers and welded it in. Used factory after muffler hanger welded to the dual Flowmaster outlets and all is hung properly and welded......sounds amazing. Truck now spins the wheels through second gear!

Nice rumble. Improved torque in a True dual, long tube header exhaust set up on my 96 Chevy K1500 4x4. Would recommend to anyone wanting to hear it roar!
