I'm back again guys. I love this Camaro but these electronics really bug me sometimes.

I'm looking at installing an MBRP axle-back and I'm concerned about the NPP mechanism that is present on the factory muffler. Can I just leave this unplugged or is there some sort of attachment I can grab that will prevent the computer from throwing a code?

I would go full exhaust in a heart beat but I don't want to void my warranty yet so the cats are staying for now.

Thanks for any input and helping to demystify this whole process guys.

Nope you'll be fine. I have the catback MBRP and all they did was just bolt the NPP valves up to the side and out of the way. No codes. BTW you'll LOVE the sound

I want the same exhaust .. but idk if I'm ready to lose the NPP function lol been stalling for the longest

[oldman]

love it, I'm old, would have to get the ones with the mufflers, but really crazy loud and no drone!

will this pass Texas inspection.

You can remove the valve actuators completely and it will not throw a code. I have this exhaust and love it, sold my Stainless Works NPP axle back because it was not loud enough, it also had a little drone but that didn't bother me. The MBRP sounds great, much deeper, louder and no drone.

I think EFI tuning are working on a module that plugs in to prevent any CELs.

I cant tell if I want to get rid of my 2ss or max it out as a daily.
is there much difference between race and axleback? I was leaning towards the race catback due to sound.

There is no module needed to prevent codes on NPP. I unplugged mine to install and ATAK exhaust and no problems. Codes can arise from unplugging the AFM modules unless you have them tuned out in the FPCM.

So I’m thinking you may have answered the question I have: if you replace the OE exhaust even with a setup made to be compatible with the NPP you will lose the ability to change between stealth and track mode? I guess this makes sense as I don’t see any wiring harness on the new setup. Be nice. I’m a girl and I’m just trying to envision how this work. I’m interested in the Borla axle back but this is the first mod I’m doing to the car (2016 2SS with NPP). I guess there is cutting of the OE involved as well? I’ve listened to the 3 different options Borla offers and like the S-type the best. Thanks in advance 😃

SSummit - How loud is the MBRP system? Thinking about getting one but don't want it to sound obnoxious. Thanks

is yours a auto with afm? if it is what did you do with the AFM valves ?
