Porsche 718 Boxster/Cayman Maxflo Catback Exhaust System

$1,845.95 - $2,095.95

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  much 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. We look forward to extracting even more power with our hardware in conjunction with a Fabspeed ECU Tune at a later date as soon as possible.        

FINISH: Full polished T304L stainless steel, beautifully welded together and finished off with hand made single-wall stainless steel tips or premium matte carbon fiber shrouded tips. Tips are interchangeable at any time.
