Welcome! As far as modding your sweet car you could probably get away with a lot here if you have good tags already. I personally registered my car in bend where there is no DEQ so I didn't do smog. My motor was still being built there when I bought the car so I chose to straight pipe it and go stage 2 at the same time. You won't have cops pulling you over cause your car doesn't look stock or if it sounds straight piped or saying anything about it if you get pulled over for other reasons from my experience.
