Oh and do you feel any power gain from the catback? I don't care too much about having extra sound if there's not much extra power for the money since I'm rather short on cash(basically I dumped every last penny I had into my car...then got some loans and my parents helped cover a bit) so I've been having to buy gas on credit(yes I'm that low on cash). Will have money again soon hopefully, but still gotta pay those loans. Anyways, I know HKS is good stuff and am kind of hoping they release a full turbo bolt on kit for our Si's....

HKS started this turbo shit up way back when anyways =P so I'm sure they know what the hell they're doing =)

(HKS produced the first commercial Turbo kit for passenger cars in the 70's or something)
