Borla atak or muffler/cat delete?
Just bought a c7 npp '17 and was wondering if you guys could help me out with your opinions.
I am not pleased with the how loud the NPP is and definitely want something done to the stock setup.
Ideally I would like to retain the npp valve function so borla atak seems like the best choice.
How loud would the borla atak be with the cat deletes vs a muffler delete?
Is the borla atak system necessary or should I just get an x pipe through the secondary cats and call it a day?
Much appreciated

Let's see, you could try the x pipe for $480 and if that isn't loud enough, then you could spring for the $2000 muffler. Hey, it's just a thought...
(like the NPP in track mode really isn't loud enough? Do you have to be that guy with the stupidly, annoying, loud exhaust when driving to the grocery store?) Even race cars have to meet sound limits...

I got an ebay xpipe for like $210 with my NPP and its louder at WOT/cold start but when cruising it isn't loud.
For the money (if you wanna spend $2K), to get the sound I'd go with ARH Midlengths. Warranty friendly and less than the Borla Ataks. They actually add power too. You also retain NPP so you can quiet it down.
I pulled the fuse on my NPP and my 70/90 year old neighbors haven't complained once.
