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?

 

just some searchin and u will find out but yes u will pass as long as u have ur cat. on and make sure the intake is carb legal which injen is...and yes the bypass valve will fit.

 

thanks

 

does the RRM downpipe take out the cat? if so thas illegal right....any downpipe that uses the stock cat???

 

yes the RRM dp does not include the cat, and it is illegal. Right now there isnt any dp that uses the stock cat, only solution is to weld in a cat into the dp.

 

the noob thread at the top of this page should answer ALL of your questions.
