Which part of the exhaust - headers and x-pipe or just catbacks? The NPP catback is actually pretty good but if that portion is what you would like to replace, check out Corsa, Borla, etc. All good products.

Assuming that you have the NPP exhaust, I would add 1 7/8" headers with high flow catted x-pipe and keep the NPP. That's what I'm running (Kook's brand) on my 2015 and absolutely love it. I can make it quiet with stealth mode or let'er rip in Track mode. Best of both worlds.

Start with a cat-less X-pipe, for me that was enough. It is an easy mod that doesn't cost too much. Just be warned cat-less X-pipes are getting harder and harder to find as they are technically an "off road" part that is not emissions compliant.
