Your setup looks similar to the one I have in mind. Have you passed your smog test yet?

The only concern is that your exhaust is no louder than 95 decibels at any point. So get whatever system fits your budget and your taste, but beware that an overly loud exhaust system is not worth the hassle here.
Thats good to hear, I like the RS*R and Evo2 so I'm guessing the tones on these are lower than the 95 d.
