Flowmaster 50 Series Delta Flow Mufflers Reviews


From 40s to 50s

Reviewed By THOMAS C (GARLAND, TX) Reviewed for a 1985 GMC C/K 3500 —4/4/2013 8:22 PM

One of the best purchases I have made. I went from the 40 series to the 50 series. I am not saying there is anything wrong with the 40 series, as a matter of fact I put a set of them on my 1985 GMC k3500 454 27 years ago. I just changed them out a week ago to the 50 series. Yes the 40s were on their last days, but I would say I got my monies worth. What other muffler that you know of will last 27 years. Needless to say they were a little too loud for me at this point. The 50s fit the bill for me

Cabin Sound

Reviewed By Glenn S (Waupaca, WI) Reviewed for a 2015 GMC Acadia —5/19/2016 8:20 AM

I like my Flowmaster 50 series muffler but i wish I would have gotten a 70 series Flowmaster for less noise, I do not mind a little noise in back of the car but cabin noise bugs me, as they say after the fact. It would be nice if there was a return policy if we the customer was not happy and was going to exchange for a similar product.
