You can start with a muffler: get M performance exhaust or Remus. If you want your exhaust to be louder with pop and cracking noises, then go for a Downpipe.
Tuning: go for Bootmod3 ( BM ) and you can do it by yourself. You just need to buy a cable and buy the license from BM3 website. There are heaps of videos on youtube show you how to do it.
Lower springs: H & R sport springs or Eibach pro kit.
Body kits: Front lips spoiler, rear m sport spoiler, black kidney grills.
Lights : M performance LCI tail light
It's gonna cost you a fair bit $$ depending on what do you want to do for your car.
Happy modding
