Flowmaster Super 40 Series Mufflers Reviews


Wonderful rumble for the best price available

Reviewed By Daniel H (Sherwood, AR) Reviewed for a 2005 Chevy Avalanche —11/14/2018 8:03 AM

This muffler sounds absolutely awesome!! It has an aggressive, deep, race car sound! And, AutoAnything blew the doors off everyone's prices. I bought it for $80 less than the local shop quoted me!

Louder than I anticipated (but not too loud). Wonderful sound overall. Very satisfied with my purchase!

Nice piece

Reviewed By Jacob P (APPLETON, WI) Reviewed for a 2011 Chevy Avalanche —8/15/2017 12:14 PM

Nice replacement that shaves some serious weight, growls low, isn't too loud. Does drone for me a bit in 4 cylinder mode. If your truck is like mine go find some 3 inch Outside Diameter piping and 3 inch inlet outlet muffler and they'll go together well
