As far as i know, which is a little, it is a chip it will not recalibrate to compensate for new parts. you will need to have shiv do custom tunning. the reason is the sensors will sense the difference of the cold air intake and the exhaust. but exede was mapped to help you car the way it was in tunning and install. if yopu add performance parts you will need tunning to get the most out of it. it can work if you wait and get an exhaust and then buy an exede with it pretunned with exhaust in mind. make sense? i don't know if the exede will self correct. but i do know that it will stop the cars chip from self correcting and lowering you power that you get from exede.
hope i helped

It's more fun to drive a slow car fast, than a fast car slow; F- That just go to driving school and you can do both.
