Exhaust bolts up relatively easy if you have some basic automotive skills. *make note, does NOT fit the Z71 trim without modification of the trim*Sounds great, not too loud, but a nice throaty growl.

I am in love with my vehicle again. The sound this exhaust puts out makes me feel like a kid again. I love rolling the windows down and hearing that sound. It is a great product for enhancing the performance of your vehicle as well. Great seller too.

Purchased this Exhaust system almost 4 years ago and haven't had anything but good to say about it. Completely transformed my 04 Yukon XL from a mom truck to a man truck. Nice clean moderate sound with great crackles in deceleration. Completely happy with this lurchase
