Hello everyone! I have a 2012 ralliart and I want to modify it slightly, I talked to my dealer and basically all I can do for upgrades without voiding the Warrenty is a drop in air filter and car back exhaust.
anyways I am looking at putting a cosworth drop in filter and I am still trying to figure out which exhaust is the best. One main question I have is if I do the air filter and a Bola Cat back exhaust do I need to do anything to the ecu?
Also does the 2012 ralliart use the same exhaust as the 2011? I want the car to have a nice low rumble to it and I like the sound of the Bola but any other options would be great so I can get a better feel for what's out there. I am not trying to be a cop magnet but I want it to sound nice!
