Well what is the max whp for a type-s with 310cc injectors?.....like 210.....with a stock cat in, that is about the max of what you will see with a jrsc-r on a k20a3.....thats another reason I am running the stock cat. It is there to restrict the motor so the 310's will work...........you want to run your test pipe, do not blame me if you go lean.
