    Awesome sound!!!!

    Shipping was a day late but the product was in great shape and worked perfect. Sounds great on the truck. I would definitely recommend this product.

    Great product provides great tone and little drone.

    Excellent quality and provided great tone and sound for my f150 5.0. Not too loud but nice low rumble and loud growl when you are WOT. Sound is high performance and low drone gaining speed, no drone at all at highway speeds.

    Good tone!

    Put this in my 1999 Chevy K2500 5.7 Vortec and it’s pretty good. Not too loud and has a good rubble. No noise inside the cab unless the windows are down but not much. Highly recommend!

    WAP Guaranteed

    Seriously though, my 10 year old Chevy sounds amazing now. Nice tone, easy to install (kinda). They should pack an optional kit with two 3” long adapters from 3” od to 2.75” od. If you don’t have one of these on your Chevy I suggest you put one on ASAP, it will bring the moisture to your co pilot 😂

    Best muffler for my 06 Chevy avalanche z71. Just loud enough, not annoying, and can't hear inside truck when window is up. No drone.
