718 Boxster/Cayman Maxflo Cat-Back Exhaust System (2017+)
FS.POR.718.SSXX
Fabspeed Motorsport USA's Maxflo Catback Exhaust System increases sportiness, aesthetics, and performance by replacing the rear exhaust section with a freer flowing extra light weight performance solution that saves a massive 18 lbs 8.2 kg.
SOUND:
The Maxflo exhaust coaxes out more of the characteristics of the boxer engine - a deeper rumble with a significantly more refined Porsche tone. This system is very livable with no droning, and the activation of Sport mode greatly increases cracks and pops during shifting and overrun conditions. Expect a slight increase in turbo sound as well - which can be enhanced even further at any point with the separate addition of our Sport Catalytic Converter. Finally the car can breathe and sound like a Porsche.
POWER:
Fabspeed's Maxflo Catback Exhaust added 4 whp and 11 ft-lbs of torque peak power gains when tested on our Dynojet on a stock vehicle. 8 whp and 11 ft-lbs at 3,500 RPM will make a significant difference in drivability. The increased exhaust flow helps tremendously at high RPM, unlocking 19 whp and 20 ft-lbs of torque at 5,000 RPM. To extract more power, we recommend pairing this system with our Porsche 718 XperTune handheld tuner
