• 991.2 engine: the 3.0L twin-turbo is different from the 991.1's 3.4L, so tuning and engine parts are not shared between them.
• Exhaust option: the AWE SwitchPath exhaust is listed for cars with the Porsche Sports Exhaust. Check your car has it.

Have a qualified workshop fit turbo, exhaust, brake and suspension parts. A turbo upgrade needs the matching tune. Get a four-wheel alignment after suspension work and bleed and road-test the brakes after brake work.
