I think the new NPP on the Camaro keeps it in the last mode used. You are absolutely correct with 2015 and below though.I think most of the bi mode exhausts in cars are that way. Chevy guys wire up toggle switch override controls, I'm sure someone will come out with something like that soon.
Hey Burndog,Anybody figured out if there is a way to change the exhaust default to "sport"? Hate having to hit that switch every time I start the car. (Only complaint so far)
The previous Gen NPP was also based on throttle position and RPM. The new NPP is based on drive mode. Might not work with these cars since its dependent on drive mode or exhaust mode, say if the circuitry for the exhaust mode is hardwired through the drive modes as well. If that is the case (not saying it is), you could really fook something up or the car would throw a CEL.I know on the 1LE camaros with the NPP exhaust you can just pull a fuse and it will stay open/in sport mode. Not sure if that's possible on the 350??
