I'd go for Kakimoto over HKS mate, Most if not all HKS exhausts are mild steel, so depending on how long you plan to keep it, it may go rusty, they also sit quite low.
I had a Kakimoto hyper Full mega N1 (genuinely what its called) on My Integra Type-R and it was a piece of art.
Cheers for the info mate!
The system i'm interested is called 'Kakimoto Regu 06&r'...lol
