I had it really bad on my '14 (also first year if a redesign). I would definitely bring it to the dealers attention because they re-apply it in many cases. I noticed the '16's and up seen to have better adhesion. Doesn't hurt to ask.
I had this in my '14, 5.3L. I left the flapper clamped open and get the resonator. It had a deep tone and wasn't too loud at all. Sounded awesome. I would just take the valve out though to prevent the fffffff sound... There was NO drove anyway. I have the 6.2L now so unfortunately I couldn't buy this again since it's 3"piping.
I had the same problem that's why I went with MagnaFlow. I had the Borla 40359 in my 14 with the 5.3. but now I have the 6.2 so I needed 3.5"... So I went with the 12909 from MagnaFlow. No regrets though, it sounds great.
I had an early 2014 truck. Build date was October 2013. It had LED daytime running lights around the halogen projector. The DRL were great but the halogen sucked. I swapped for HID. Million times better. Take a picture of the lights on. Hard to tell from this picture but those don't look like SLT headlights to me. Looks like your missing the LED DRL. VIN or Carfax should identify your trim as well. Not sure if someone said that already. Thanks, Jon
The power stops are excellent. Z36 truck and tow pads and drill and slotted rotors. I've run two sets so far. Night and day improvement over stock. I tow a 7600lb TT so I needed something better that didn't warp in one season. Thanks, Jon
