By replacing the rear exhaust section with a lighter performance solution, the Fabspeed Maxflo exhaust from Motorsport USA enhances sportiness, aesthetics, and performance for the 2017+ Porsche Boxster/Cayman 718. This results in an 18lb weight reduction and improved flow for maximum efficiency.         



Unlock the full potential of your Porsche with the Maxflo exhaust.

Experience a deeper rumble and refined tone while avoiding drone, and enjoy increased pops and cracks in sport mode.

Expect a slight boost in turbo sound that can be further enhanced with a sport catalytic converter. Let your car breathe and sound like a true Porsche.



Fabspeed's Maxflo catback exhaust added 4 wheel horsepower and 11 lb/ft of torque peak power gains when tested on a Dynojet on a stock vehicle.

The added 8 horsepower and increased torque of 11 lb/ft at 3,500 RPM will have a notable impact on the car's performance. 

The enhanced exhaust flow significantly improves performance at high RPM, increasing wheel horsepower by 19 and torque by 20 lb/ft at 5,000 RPM.
