need help on stock exhaust

how would a stock exhaust sound with pacesetter headers and ory, cause im considering headers but have a completely stock exhaust and it will be a month or 2 before i put cat-back on it so im wondering what im getting into for the next couple of months

any video clips??

oh by the way its an 02 z28

It'll sound good, the only thing to take into consideration is there will be some modification needed to merge the 2.75" i-pipe to the 3" y-pipe.

k i didnt really think about that but now i can plan ahead ill prob jus buy a pipe that goes from 3 to 2.75 from a muffler shop temporarily
