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

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

Flowmaster 50 Series Delta Flow Mufflers

Reviewed By George G (PALMYRA, VA) Reviewed for a 2014 Ford F-150 —6/8/2017 6:56 AM

I bought these to replace the S-mufflers that came with my Stainless Works exhaust. They were fun just running around but much too loud for pulling a trailer for a 1000 miles up and down the mountains of WV. These fit the space perfectly and have a very good rumble with out overpowering the inside the cab. Wish I could have gotten them in stainless but they are well made and should last a long time. Just be aware that both inlet and outlet are ID. Great price, very pleased with results.
