So im looking to get exhaust for my speed 6 and i was wondering what is best. I know im going to run a 3" pipe but im wondering if i should do a catback or just straight pipes. Whats going to get me the best flow and stay away from the rice rocket sound.

 

Also i was wondering if i do a downpipe i will have to remove the cat. If i do that is my car not going to pass smog and will it throw cel. What is better to run a downpipe or a testpipe?
