exhaust help.
Hello. I'm currently running the hr intake and the aem cai calibration with no issues. I am about to purchase the q300 exhaust. I do not want to purchase an e tune until after I buy my header. I guess my question is can I still run the same calibration with just an i/e? My vehicle is an 09 fa5.
