SpeedART have a number of upgrades available for Porsche vehicles.

They have a new active sound module for the Porsche Cayenne and Macan diesel vehicles. This system has a three step set up and creates a sporty sound like a V8 engine. Here is a video of it in play.

Another upgrade for all Porsche 991 Turbos is their plug and play power box which increases the performance of the vehicle to 620 Hp.

They also have a performance exhaust system for the Porsche 964 Carrera which is made of stainless steel with sport cats. This system increases the power and gives the Porsche a sporty sound. Heating is optional for the exhaust and can have one or two tail pipes depending on the rear bumper.
