Flowmaster Street Performance Mufflers Reviews


Flowmaster 70

Reviewed By Tim W (MORIARTY, NM) Reviewed for a 1999 Ford F-450/550 —3/27/2014 12:31 PM

I installed the Banks headers on my 99 Class A MH and wasn't about to spend another $500 to replace a perfectly good exhaust pipe. The muffler had to go though! I purchased the Flowmaster 70 series to replace just muffler since this was the last culprit of restriction in the stock exhaust. I wanted a quiet but unrestricted muffler and I got exactly that. It has a deeper sound than the stock but it's still quiet. It fit perfectly and a great price as well. Tim

Flowmaster 40

Reviewed By Larry B (Garden City, KS) Reviewed for a 1990 Ford F-450/550 —3/1/2014 6:20 AM

Best thing I can say about the Flowmaster is that it was made in the USA. Good product; easy install, affordable, got to me in reasonable amount of time. Thanks

Magnaflow Performance Mufflers Reviews


Magnaflow Stainless muffler

Reviewed By Steve L (Sullivan, MO) Reviewed for a 1997 Ford F-250 —6/30/2016 2:56 PM

I narrowed down the list of mufflers to two (2) for my Ford 460. The first was a Gibson MWA. Nice muffler - but too loud. I settled for the Magnaflow. Once the exhaust was installed with a rear-exit tailpipe, the 3"in/3" out centered muffler had a low-rumble with no indication of resonance inside the cab, even while downshifting from a higher rpm range.
