Help and advice for cold air intake and exhaust system.
 

Hey guys and gals. I been doing a lot of research lately to install a HKS Super Power Flow Reloaded Kit (Green, 200 - 100). For a R33 GTS Sedan with a RB20E engine. I am certain it fits my car but I have to make sure from the people here with more experience, also what muffler exhaust should I choose for my car, haven't done much research on that but I might as well ask anyway. If there is anymore advice or ideas, that be much appreciated. Thanks in advance.
