How does the truck run? Just picked up a 2014 last week and I have the bug already to do some upgrades. Plans so far might be a set of long tubes, stock exhaust and replace the stock muffler/flapper valve with a Borla Pro XS and I'm really looking at the L86 manifold swap and then tuned obviously. I've been looking at TSP and SE on the headers. Seems I'm going with 1 7/8 as I wont spend $1000+ for ARH 1 3/4

Amazon has the best price on the manifold. about $120-130 after shipping.. don't pay $270 for one. Lol
*EDIT* I see you combined the price for all three. But yeah, not bad at all compared to some OEM manifold swaps for the LS's.. I will probably go with long tubes first for mine.

Huge difference in power/pep in it's step with intake headers exhaust and tune.
That's what I've done and where I'll be leaving it for a while.
Bgbldodge. If you don't want it quiet you wont want the stock 6.2 exhaust with the stock mufflers. Everything on my truck is louder than the 6.2 catback. The intake, the road noise etc lol. But I didn't want mine loud so I like it. But if you get one and cut in your own muffler it's a bargain for what you get.

Having cats will help keep it quiet too. They actually quieten down the exhaust a ton so you should be okay. I don't know how loud that borla muffler will be though, I imagine kinda loud compared to the stock muffler because the stock muffler is half the size of the truck, not really, but it's huge.

I slaps right on the truck the only issue you will have is where the pipes meet. The 5.3 exhaust is 3" and the 6..2 3.5" at the end of the y pipe where the cat back bolts up, so you'll need some sort of adapting there.
The speed engineering headers come with two adapters to fit either catback so if you have those headers you can just stick the exhaust right on.
Main problem with using the 6.2 cat back is a lot of guys keep the specific clamp for the ball socket flange. I had to have my flange welded cause the guy kept the clamp.
