My 2014 SLE Double Cab with a little work done
 

Went from an 07 RCSB NNBS to a Buick Regal GS to a 2014 SLE Double Cab 5.3L 2wd. I put an Airaid intake on, Gibson super truck exhaust, 3" Belltech lowering shackles (PN 6401), 2014 SLT/Denali knock-offs wrapped in Nitto NT420s's. Love the truck and have had zero issues (or fires) so far. The factory 20" wheels are on Ebay right now if you're interested. Custom Tune by Tampa Tuning is next.

Dayum that looks killer!! :drool:

Looks good. How's the ride with the 3" drop shackle .

No noticeable negative side affects so far. Haven't hauled or towed anything heavy yet though. The rear is still 3/4" higher than the front.

How does the truck sound in 4V mode with your exhaust?

Looks good but you shoulda kept the OE 20's imo

Pics of the intake installed.

can't really tell from my own experience... with my '08 and exhaust when it would go to v4 mode I could never tell any difference rolling down the highway.

interested in OP's reply though, I'll be doing exhaust on mine real soon.

It sounds about as good as it can IMO. It actually sounds like a smaller V8. I think the sound is slightly more distinct than my previous truck (I had this system on my 07 NNBS RCSB) and I notice it a bit more but I think it is just my perception since I am coming from driving an ultra quiet Buick Regal GS. None of my passengers mention the V4 sound and I had to point it out to my dad who could then identify when the engine made the switch. For the $350 I paid or the system I am completely happy with it.

I was on the fence about making the switch to be honest. Those stockers just didn't blow my skirt up. They looked to small (but I suspect it is the new shape of the wheel wells that make 20's look small). I was worried about these having too much black in them and the truck looking 'murdered out' as the kids used to say. In person, the wheels looks great and give it a presence the OE 20's didn't. IMO.
