Are you looking to get an exhaust similar to Oem looks, or is that a factor that matters? What is the price range that you would like to spend? I'd suggest the Dynomax Super Turbo Exhaust system if your looking for a budget setup and near stock oem looks.
Sound and looks don't really matter as long as its not obnoxious, right now the car sounds like a formula 1 car in the higher rpm range
Go with a custom setup from SMSP. They can custom make an entire exhaust system from header all the way to the muffler specific to your setup and needs.
