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.

 

Exhaust and intake are easy mods to do. Exhaust will never void the warranty and an intake can be switched out easily if necessary for dealer work. An aftermarket ECU upgrade can also be easily removed.

You can get a JCW kit but they are very expensive. Or you can just buy some of the JCW parts like exhaust and intake

 

I have an '04 R53 with an extended warranty and that warranty is the only thing that has prevented me from doing anything fun to the car.

 

Best bet would be to throw this up in the 1st gen forum, since you have an '02. You'll get a better response there than you will from us R56 guys.
