awesome muffler

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

Jon · November 17, 2025

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.

Overall a good choice. Sound is appropriate for the vehicle (1500 Trail Boss). Not too loud when driving normally but will make some noise when you step on it.
