5.0 Cat back system

Took 45 minutes to install. Makes my 15 Silverado sound better

5.0 Great sound, not as loud as I thought it would be

The outlaw exhaust is not very loud in the cab of the newer trucks if you like the sound of the engine.. the Silverado AFM system sucks and will be deleted soon. Great product.

2015 Silverado 5.3l
4.0 great looking and sounding but has small issues

The box showed up DESTROYED. I was surprised i wasn't missing pieces. The exhaust looks and sounds great.easy install for the most part. some pipes were a little too big to fit snug over whatever pipe they were connecting to so I had to use a clamp and tighten it around the pipe off the truck to get it to be snug. clamps heat up so the expand for a few days after the install so youll need to keep checking and tightening them until they stop getting loose.
