Flowmaster Super 10 Series Mufflers Reviews


Best $140 I ever spent

Everyone thought it be loud and obnoxious so they were trying to convince me to just settle for glasspaks.... And am I glad I didn't... This thing is MEAN and very aggressive since I got two coming out, dumped at the axle complimented with headers... I recommend these mufflers to everyone!

Unbelievable

Reviewed By Jonathan V (Saint Paul, MN) Reviewed for a 2003 GMC C/K 2500 —7/6/2010 2:59 PM

I've got a '97 Sierra with a 5.7L V8. Put a cold air intake on it, and that made it pretty fast. This exhaust kit is everything I've ever dreamed of, and then some. The noise level is perfect-not too loud, but not too quiet. I've only heard it from the cab, but I'm pretty sure that on the outside, it grabs attention. Now, with that classic American growl, it's stupid fast. Very smooth, engine runs so much better now. Fuel economy looks extremely promising... haven't had much time to get a good reading. I've just got to find some F-150 drivers that are brave enough to race!

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.
