I bought my Evo deflectors off eBay, I didn't search for anything specific other than that they were for an Evo. In terms of exhaust look into raggazon, stainless steel and sound good for the price. Alloys I'm not expert on but BBS alloys are quiet nice. For other mods you could get a filter? I have the BMC panel filter, same as the supersport, however mine only increased the sound of my turbo not so much induction sound.
