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

Flow 44

Reviewed By Mark H (ANTHEM, AZ) Reviewed for a 2011 GMC Yukon —10/29/2015 10:11 AM

Had a magna flow on muy Denali w/ 6.2 liter . So glad I changed it out with a flowmaster super 44. Now it sounds great and seems to be getting better mileage as well.

just right

Reviewed By Tim R (RADNOR, OH) Reviewed for a 2015 GMC Sierra —6/30/2015 5:52 AM

the 50 muffler is the right one for me and my sierra. it is just loud enough to let you know there is power under the hood, but it will not vibrate inside. unless you punch it, you would not notice it much. you can tell in normal driving it has more torque and horsepower.
