Sport Exhaust System Turbo-Back
with integrated Exhaust Flaps 
- for Porsche 991.1 Turbo / Turbo S
- for Porsche 991.2 Turbo / Turbo S

When the flaps are fully opened, 35% of the exhaust
fumes flow freely out of the outer tailpipes. The sound
is breath taking!

This turbo-back exhaust system has been developed and
tested to the highest standard on the dyno.

It is designed as an absorptive silencer inlcuding a special
catalytic converter set, coated in a Tri-metal material, which
is fully OBD2 compliant. No CEL (Check Engine Light)
and No DME/ECU programming required.
The result is besides more power and torque a better
response characteristic. 

Further evidence of improvements made, are recognised 
through an enhanced accoustic and weight reduction. 
Strenghtened brackets as well as the olive- and slide 
system ensure an exact adjustment, which guarantees 
a stressless installation.

New modular design with the possibility of interchanging
components. Developed for maximum flow this unique
CARGRAPHIC part creates the following further advantages:
- Reduced backpressure
- Reduced temperature
- Maximized performance
- Enhanced sound
- Weight reduction
- Lasercut machined stainless steel flanges for accurate 
   plain fit
