Was very happy with overall installation hardest part was getting the 12 year old spare down ... that's never been done. The only problem I had was with all the clamps neither the 3" or 2 1/2" would tightened down enough, even broke one of the bolts trying to secure the pipes. So some one needs to review the clamps or contact me as I am a disappointed in that parts also you say complete installation then you need to include 2 more rubber hangers as just the 2 in the package are not enough.
Flowmaster Outlaw system
Installed Flowmaster's Outlaw system on my new 2016 Chevy Silverado along with a K&N Intake. I immediately noticed horsepower gains and better fuel mileage. The only negative issue was noted during installation. The pipes did not properly secure onto each other with the provided clamps. You are required to spot weld or modify the pipes by cutting an opposing slot to the one factory cut, which will allow the pipes to secure onto each other with provided clamps. Flowmaster is aware of issue.
