Finally bought a Borla x pipe from a great forum member and installed it on my 2017 z51 yesterday. Wow it Sounds amazing, it’s day and night. When you give it WOT it sounds like a whole new monster. Def happy with my results. The idle is a bit louder but not obnoxiously Annoying, maybe I’ll pull the fuse on my npp and see how that sounds. Only other mod is a Afe intake. The two make a good mod
Awesome! I'm doing one of these soon too. Why did you have to pull the bumper? Seems like you would be able to pull it without removing that cover (Was the scissor jack in the way?)
Very nice! Apart from sound was there a worthwhile noticeable performance increase? Do you think the secondary cat deletes provide any less restriction? Any issues with OBD codes or warranty in your opinion?

Def feel a difference in performance but could also be because of the afe intake aswell, the two mods should add a somewhat decent performance increase. No codes were thrown And shouldn’t because rear cats are not monitored. From reading here on the forums the x pipe shouldn’t affect warranty but don’t hold me to that
Overall I think this is a great mod for the C7

I put a Borla X-Pipe on last fall. Not real noticeable sound increase at idle or IMO even with normal driving, but definitely a significant difference at WOT.
I personally don't see any performance increase with the "butt-o-meter" but on a clock their might be as no doubt the exhaust flows a little more freely without the unmonitored cats.
As reported here by lots of members, no CEL's or other lights as the cats removed are not monitored.
Warranty issues? I kind of think it depends on your dealer and if they want to be picky. JMO. My local dealer service writer that has taken very good car of my car (a car guy himself) said he could care less, not a big deal.
Why'd you pull the fascia? I did a Corsa x-pipe last month and no reason to touch the bumper. Sound improvement with the stock adjustable mufflers is great.

Yep,had a different xpipe that had resonators at the front, and just recently went with the borla x pipe and for me personally the sound is a bit deeper and love it ,and such an easy mod to do especially with my quicklift ,made it a breeze
Yea there wasn’t really a need to remove the rear bumper. Kind of did it more out of curiosity then anything else. Install was a breeze. Def enjoying my c7 even more now after install
I read your reply and used your link -- thanks. Even though I already have the Borla installed and think it's a great mod for the money, I still learned quite a bit from the link that I didn't know -- great write-up and pictures -- thanks for your time and effort. -- tom
