Need advice for Del Sol - I'm new

Hey guys, I need some advice (I'm new)
Hey - I'm new on these forums, but I just recently (3 days ago) bought a Honda Del Sol Si (VTech) in the Pearl Green color w/ a manual tranny.

I like it, but even w/ the VTech, it still isn't fast enough. I've already put on a generic intake kit, (and altezza tailights), but I want to replace the ENTIRE exhaust system, from the Headers down. Can you guys recommend any exhaust kits/systems? I've heard that VTech engines need special headers because they use the backpressure to help the VTech system.

Any advice would really be appreciated.
