Hi, I'm new to this place, I just got a MCS 02. I have an extended warranty on it. So my question is what performance parts can I throw on it that will either not void my warranty and or things that I can do to the car that I could either take off or put on easily, if the car needs to be fixed? Also If I did put on parts would a mechanic be able to tell that I had after market parts on there. Also is it possible to get JCW parts (cause I know they don't void warranty) like a smaller pulley, exhaust ect? and if this is a re-post I'm sorry I looked but could not find anything.
