Hey guy's
Thanks for the advice.
I went to summet's web site and by the time I put in what all I have on my car I only have a few choices. Not sure why but it seems likes air and power brakes seem to eliminate a lot of choices.
All I care about is getting some that are ceramic coated. I put these on my 2011 Camaro and like the way they look. I'm not looking for performance. I just want some good sound and eye candy under the hood

IMHO Racing bullet mufflers with staight dual pipes, as any type of cross over pipe will cancel and blend exhaust pulses.

My father's 72' has Dynomax ceramic coated headers. His car has a/c, power brakes, power steering, etc. No fitment issues, one small a/c brace had to be trimmed. Otherwise a direct bolt on. HTH
