I would value your imput.Finally got my camaro. Wanted one since high school. Graduated in 1979. Want to stay street legal. Bought the GMPP performance exhaust was looking for sound and performance, got the performance but sound still not there. Was gonna get the factor headers and just found out that they are not going to produce now because they wouldn't pass emissions. What do you suggest. I want the sound and performance, and still be able to drive my baby up and down the streets.
