Is this a GM OEM NPP dual mode exhaust system from a corvette model year 2008? You mention it is from a 2007. Did you remove your original 2007 exhaust and install this?

I'm still not sure what you have for sale. Do you have any pictures? I have a late model 2007. My car was built in May 2007. The last month of the 2007 build was June. I am pretty sure the Dual Mode NPP exhaust system was not available on a Corvette until model year 2008. It is the only year that it had 2.5 inch pipes. After 2008 GM went to 3 inch pipes.

Looked up into the exhaust and their is a baffler or flap (metal) that looks like it opens and closes?
Thanks!!

From the factory they don't have a switch. They open automatically . You can add a switch to open them easily.
