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.

Reviewed By Paul D (Rialto, CA) Reviewed for a 1992 GMC C/K 2500 —8/24/2015 8:34 PM

This unit solved my issue in passing the California Smog Test... A 1992 5.7L is as clean as any new car today! (HC= 14/7, CO=0.03/0.02; NO=299/34) WOW! I should have replaced my old Catalytic Converter & O2 Sensor units first and stop worrying about the test results.

Flowmaster Super 50 Series SUV Mufflers Reviews

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.
