Hey guys. I have an 04 auto RA that I am thinking about doing some minor mods to. I am looking into getting the injen CAI and a 2.5'' magnaflow catback system. I was just making sure that I could still pass smog. I was also wondering if the AEM bypass vaulve would fit on the Injen CAI. Thanks

 

Would i loose any torque by adding the exhaust?
