im assuming ur talking abt the J's corp. special? from the youtube clip?
i havnt seen anyone with that; dont even know if its legal to have on a s2k. is it a RR or a RS? can anyone confirm.

realisitically speaking; s2k exhausts arnt the cheapest.
id say they'd set u back atleast 2k; and can go up depending on material used. the top end material/brand to 4k.

as for power gain; honda has tuned the s2k to its maximum effciency; you are not going to get any real gains for this kinda money. heres a post on s2ki with buddyclub spec exhaust:

the gains were 5kw, and considering the price u might second thing the change. but mind u After market exhaust weight anywhere between 7-11kgs where as the OEM exhuast weighs 25kgs...

just a thought; how long have you had the car? why not just drive it as it is for a while get used to the power and then change a few things; you would probably notice the change more if u had the car for a while. but yeh
Long story short; its not going to be cheap modifying the s2k; personally i think it was never made to be modified; if honda did anything right, it was the s2k from the factory its impeccable.


just my 2c
