I see what your saying but like K&N and prefer to use it on all my vehicles, and using them for years I didn't replace the catback its the factory upgraded dual exhaust not even sure if its even a full catback setup that's why I was asking. only other exhaust planning to do is long tubes which will net me good results as well, and maybe cam and reworked intake and heads in the future.

You should have done some research.
they are one of the WORST ones on the Camaro flat out..
There is some required reading here that shows all the test results of the Camaro CAIs. the K&N was very very low.
And I was actually talking about the cat back you said you replaced.
The NPP is the factory dual mode exhaust which is the same they put on the ZL1 and the 13 2SS M6 cars.
Good luck, before modding any more I'd suggest reading a lot in here to get the best bang for your bucks.
