I have the SLP on my truck. It sounds decent, but I thought it droned a bit too much. I purchased a 3" Vibrant resonator for $85, on Amazon and cut it into the pipe when it comes back down over the axle, same as stock. Fixed about 90% of the drone. Just so you know, the SLP comes with 2 inlet pipes, so you cut it to fit your particular truck. It's an easy install, I did it in the garage on jack stands. It comes with nice band clamps, and seals well. The Vibrant resonator is about an 1" too long for the stock location, so I cut 1/2" off each side and made my cut into the SLP over axle pipe. It slips on the outside of the SLP pipe, and I cut 2 slits into to the inlet and outlet of the resonator. I used U-bolt style clamps, and it worked well. It sealed pretty good and didn't have any leaks or movement, but I went back a few months later, when I got some flux core SS wire for my welder and welded it up permanent. You could get away with not welding if you wanted. I hope that makes sense for you.

imiller1974 replied to zzach19's topic in 2014-2018 Silverado & Sierra ModsI have a 2015 CC 5.3 with pedal # 23362231. I've had the truck programed by Black Bear, and the pedal still feels sluggish. Probably the sluggish feeling pedal of any vehicle I've ever owned. My 2014 4.3 pedal felt similar. It's been about my only complaint with the truck. Black Bear tune helped with it, and with the tranny shifting, but not as much as I had hoped for. I guess it's just the nature of the beast(our trucks).
I had a 2014 DC W/T 4.3, 4x4. Traded it for a 2015 CC LS 5.3 4x4. I like the extra room in the cab for passengers, and don't mind the shorter bed. I built a hitch extension and when I use staps from the end of it, to the tie down points in the bed, I can haul 16' lumber decently. I tie a flag to the end of the lumber. The hitch extension has reflectors on it. I have noticed the DC's are usually cheaper the CC's, more than I thought they would be.
