My buddy owns a 98 Prelude SH. He was wondering whats the best exhaust system for his car. (best gains) and also which intake would be better; Short ram, full cold air, or like a AEM V2... since the forums were reset i couldnt find anything in searches. Also he wants to know which clutch would be best...whether ACT, Cetreforce, or like clutchmasters. Drag/street use..

Any help is appreciated.
