The cat is amazing now with all stock apart from k&n filter. Which sounds nice (you can hear turbo spool).. cold air is important...
(Dont understand people with xxx air intake and open housing to let hot air come thruu filter all that heat from engine.. which is stupid.. makes car goes worse...)
The ambient air inside the engine bay is not as hot as the intake air will be when it passes through the turbo. This has a bit more logic on a vehicle where the air within the intake system isn't going to be heated or cooled anywhere else before being mixed with fuel. On our cars, we bring it in, heat it up, cool it down and then send it to mix.

Is there an actual K&N CAI for the vehicle? I've only see drop in filters. I'd go CAI (or resonator delete perhaps) for the sake of hearing tttuuurrrbboooooooo.
