New exhaust setup in progress
I got some NPP mufflers at a cheap price today from a local guy that took them off his 1LE. I currently have a muffle delete which doesn't annoy me but it's starting to get old. Anyone know where I can get a rear bumper for quad tips besides the dealership? Also should I replace the H-pipe for a X-pipe?

I have factory npp on a 15 1LT RS I took off the h pipe and resonators and put an X pipe in. Then made a mild to wild switch to control the flaps. I love it. Look on Summit Racing, Phaseteck, GM PARTS GUY and ebay and others for the rear diffuser. I've seen them from $150 up to $1,500 there's more than 1 style also. ZL1, Z28, not sure what they're all named.

1le diffuser is the cheapest, Zl1 is 2nd (1le diffuser with heat shields), and Z28 is a different design and $$$

Yes. Remove the resonators and stock H and add the Magnaflow 11386.
22829477 is the part number you need for the diffuser. It's $140 on gmpartsdirect. I also recommend grabbing the NPP in a box, and maybe the brake booster line for the V6 with NPP so you have an easy way to pull vacuum.

Bringing this back up since I'm hoping to get the mufflers on sometime this week. Got a quote from one shop for $275 to install an x-pipe and npp mufflers. Another had told me about $600 for double x-pipe, mufflers, and changing the exhaust up to 2.5" if I remember correctly. What should I really add with the NPP mufflers?

I'd do the Magnaflow 11386 x muffler in place of the H and run actual 2.5" pipe to the NPP mufflers.

Throw on the Magnaflow Resonated X Pipe #11386 in place of stock H pipe. I believe you need the NPP in a box for your mufflers to work properly. I’m not too sure if the piping near the mufflers on the 1LE are 2.5”, but I’d just stick with the stock size. The $275 deal is all you need for a nice setup.
