Apexi exhaust is the one mate, loved mine but they do tend to rot so just keep an eye on it With the mods mentioned above you will want an adjustable actuator too, you will be getting fuel cut otherwise, the next step then is a decent boost controller and a piggy pack to remove the fuel cut or an aftermarket plug and play ecu. Dont get a Fuel cut defender, I wouldnt go near one even with a FPR and decent set up, you get more gains from the ECU obviously. Very nice V by the way, enjoy
