4 inch Thunder Muzzle Diesel Muffler Gen 2

Outstanding product! My install was super easy and the wiring took no time with the provided guide and plug and play harness! Giving demos often, which are well received and wil likely create more sales!

Great product, fast shipping and amazing craftsmanship

Good tone, both fully open, closed and in between. Best modulating muffler on the market. And worth the price tag! Made in the USA!
