I own a 2001 c2 and was thinking of making it quicker.

How will a PSE exhaust work with aftermarket sport cats and headers. can this be done? i love that pse and like the switch option. porsche does not offer cats and headers from what i know.

Second will a fabspeed cold air intake do any good for hp increase.

Giac tuning a good idea ?

i do not want any mods that will affect engine durability etc..i need regular safe mods.

please let me know if this is a great way to start.

You need a system of modifications that have been tested and work together as a system. You cannot ala carte this and hope to see a change other than a much lighter wallet. I would call Steve Weiner at Rennsport Systems and see what they have for your car.
