Hi mate,
hmmm, nice questions!
As far as the question concerning Kleemann catalyst, check page no. 6 under exhaust section of the Kleemann pricelist.
As far as the intercooler question just check these links and read the comments of this guy! This guy saw 14hp (if i can recall correctly) improvement on the dyno Maybe i will have to contact him to ask more...
