Headers and exhaust
Hey all, not sure if this belongs in the newbie forum, but I figured since it was a bit more specific to camaros I'd throw it here.
Anyway, I've got a bone stock 02 Z28 (with the exception of a magnaflow catback) and I'm looking into getting a set of longtubes. I'm debating between a catted or off-road Y-pipe (Would love to get a set of Kooks duals, but 1800 is a bit out of my price range), and I ran into a couple of questions.
Number 1: I live in Washington, and unfortunately in an area that requires emissions testing. Since it's OBDII, I know they don't do a sniffer test, but, without cats, is it possible to tune the PCM so that when they plug the scanner in, it'll still pass (assuming of course they don't do a visual inspection)?
Number 2: I've heard a lot of people talking about clearance issues after lowering, and I was planning on dropping the car 1-2". Are the only times the LT's scrape when going over speed bumps?
Lastly, Would I see much of a power difference if I just waited and got the Kooks duals?
Thanks all!

I believe you can tune the PCM where it reads the rear O2 sensors as fine and actually eliminate them. I'd cintact a reputable tuning shop in your area to double check, as I'm sure they know the local laws.
