hmm, it depends.
for looks, you can get the euro clears if you dont have them already.
or for performance, an intake or exhaust is a great place to start.
for exhaust, there are a lot to choose from. do a search, people on ths board run remus, supersprint and eissimann, to uuc and active autowerke or go with tuners such as acs and hamann. lots of good info and opinions to help you decide.
for intakes, people like gruppe m, dinan, ecis, benfer... and other.
do a search, there is a lot of good info.
good luck bro
