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.

Flowmaster 70

Reviewed By michael t (NATIONAL CITY, CA) —5/27/2016 8:21 AM

I am very satisfied with the Flowmaster 70 lock monster. Great sound installation very easy would recommend this type of muffin to anyone who owns a Ford pick up our SUV vehicle. Makes my Ford sport Trac sound like a very high performance vehicle.
