Highly Recommend
Installed on a 2010 Tundra V8. Great sound for the price.

Louder that I wanted but sounds great.
It is pretty loud in the cab between 1700 and 2000 rpm. Quiet enough when cruising over 60mph. Nice deep tone with no crackle or snap. It is shorter and the inlets are wider than the factory muffler, so a short length of shaped pipe is needed to be welded in to compensate. But overall it looks good and sounds good.

The flow masters does not fit the pipes that’s on the vehicle already the ends on the floor. Masters are too big. I would like a refund.

Flowmaster master is as dependable as any brand you can name. You buy it for one reason, that sound. The fact that it’s quality built to last and great value are the bonus. Swapped out the dual 2.5” in by single 3” out 50 series for the same configuration but a 40 series! It my truck sounds so nice and deep now but not too loud still at idle. Great engineering!
