    Stainless muffler

    I wanted a second muffler on my home generator. I wanted it stainless steel and quiet. This one is well built and really cuts down the sound. Very fast service and it was just as advertised.

    Straight pipe

    Went from straight pipe that was too loud and obnoxious to adding this muffler and it put the sound right where i like it. No droning at highway speeds. Quiet enough that i can hear my engine but still loud enough to hear the performance of the truck. can't compare to stock muffler though didn't have it when i swapped

    Worked well

    It performed well at decreasing the drone from my truck while still sounding good.

    It’s not any quieter than the muffler that came with the race profile kit, it just may slightly stifle the burbling sound when letting off the throttle.
