ZL1 exhaust swap. C.E.L with NPP delete?

Supercharged Dreams · 06-09-2018, 09:31 PM

Just picked up a 17" ZL1 after selling my 2010 2SS about 5 years ago. Love the car but I want this thing to bark. I am looking to go with the MBRP cat back. With deleting the NPP system will there be any codes thrown or do you simply disconnect and tie wires off to the side? I believe they come with a plate to go in place of the NPP module. Just don't want to tune the car yet. Thanks in advance for any tips. Great to be back in a 6 Gen!!!!

Just pull fuse F51 to keep NPP baffles open. They are just in from the outside pipe tips.

It will not throw a code. I wrapped the pig tails up in electrical tape super good and zip tied them up and away.
