Well just starting to look into a few upgrades so thought I'd ask a couple of questions about what's out there so

CAI: Which is the most popular and not over the top cost wise.

Exhaust: Only one I can seem to find is the Milltek system, which I know are quality, what can I do if I just want to get a little more noise until I do the whole system, resonator delete or rear muffler, I've also heard of a turbo muffler delete, where can I fine these and what difference does it make?

DV: GFB's make a upgraded one, also found a Forge one and they also seem to do a kit to use a more conventional BOV, which is better for these cars?

Tunes: Found a few generic ones but does anyone custom tune them, I'm in Melbourne

Suspension and wheels: KW seem popular, anyone run BC Racing coilovers? I know they are cheaper but quite a few run them from the XR5 club I was in. Also anyone running 18's instead of the 17's and did it imporve the handling and what size tyre are you running?

Sorry for all the question, I trolled though pages and pages trying to find answers

So far I've ordered paddle extensions and a vwwatercooled sticker
