Just saw a fellow members is300 for sale on the forums, on it he has a Injen Intake, Megan Headers, with a Blitz NUR full catback exhaust. How much of a hp gain do you think that is? a fairly noticible increase in speed?

I'd say if you are going with a 50 shot you would be ok as long as you set it up right and use it correctly.
