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

Quiet Power

Reviewed By Carroll J (Palm Springs, FL) Reviewed for a 2016 Ford F-150 —5/14/2017 6:00 PM

I have a MBRP 4 inch system on my 2016 Ford F150 3.5 ecoboost, System gives great power but is loud as heck. When the original MBRP Muffler split at the seams I decided to give this a try. It's perfect. No raspy ricer whine or drone, It's deep and throaty, and not loud. Doesn't sound like a V8 obviously, but doesn't sound like Ricer Crap either.
