MagnaFlow 5 in. x 11 in. x 22 in. Oval Straight-Through Performance Exhaust Muffler 12589

awesome muffler

Sounds great. Much quieter than my old Flowmaster. Very well-built in appearance. Made in America!

The quality of the muffler is top notch. Having the muffler installed 1/15. So haven’t got to hear it or see if there’s any performance improvements. I have a smaller magnaflow muffler on my other truck and it sounds awesome. I did buy a larger muffler this time hoping for just a little quieter sound. One truck is a work truck and the other is not.

Exactly what I wanted for my silverado. Great sound when you get onto it. Noticeable increase in power and better gas mileage. My only regret is not buying it sooner.
