Thought you shouldn't do exhaust because if you buy one for the N/A you'll loose and/or if you buy one not for N/A you'll loose which is why it's better to wait? I love the way my s-13 looks, screw the conversion stuff ;/ Anywho, the reason I asked is for stuff like brakes...wouldn't it be better to get them before you do the swap so when you have the extra power you will already have the needed extra stopping power?
