With that being said, the same car (George's ITR) made 182.xx whp with the following mod's. Using the same "160 hp" number from above means a 22 hp increase. (just to note, I am pretty sure Georges ITR only made 158 hp in stock trim)
SMS catback - $500 (estimated cost)
OEM JDM ITR header - $350
SMS Carsound cat - $125
Comptech Ice box - $169 (new per Comptechs website)
Total - $1144
So, $1144 / 22hp = $52 per hp increase. Not too shabby for less than $1200.
