But after a few reviews and people saying it’s worth the money, I finally pulled the trigger and bought it. I would agree with them and say, although it is pricey it is worth it. For high-quality parts with easy installation, aggressive tone, and sound when on the throttle with no drone in the cab, well worth the money to have a comfortable ride and clean sounding truck

After putting 1,000 miles on the exhaust, it sounds amazing!! I also purchased and corsa closed box intake beforehand. The two items compliment each other gracefully! Everytime I turn on my truck some thinks I'm showing off 😎

The cold starts are insane and idle sounds have a deep low growl. I highly recommend purchasing an AFM delete as it has an annoying tone when it switches to 4 cylinders. Other than that I couldn’t recommend this kit enough. Build quality and sound quality are unmatched. Also it’s very mellow in the cab but very rowdy outside the cab.
