what are the cheapest upgrades to get to be able to use the stage 2 cobb tune? i originally intended COBB DOWNPIPE AND HIGH FLOW CAT

 

i think you should look around a littleeeeee bit more before you post something lol

 

Try to pick up some used Ultimate Racing parts if you can (downpipe, test pipe and catback).

Ultimate Racing short downpipe/testpipe (or high flow cat) are the same on the EvoX. You can look in both forums.

Cat-back might a bit tougher to find because it has to specifically made for the Ralliart.

I suggest going with the Magnaflow. A bit better quality than the DC and typically cheaper.

I picked up my whole turboback for less than $800. Used UR short downpipe (barely used) for $130 local here in Montreal, used UR test pipe (almost brand new) for $60 local here in Montreal and I bought the Magnaflow from a performance shop here who carries their line for like $580.

 

Man this has been answered like 100 times on here. and it says it on Cobbs site too. Look around on here for different exhausts and pick one. Go with Ultimate Racing IMO.

 

Well COBB says you need a turbo back exhaust for a stage 2 tune. Apparently a member of this site called up COBB and asked the same question and a rep. told him that you can get away with just a high flow cat. Other then that you can't have any intake or BOV or even a upgraded intercooler. Doing such can make the car run lean or cause detonation which can damage the engine.
