PORSCHE 997 Carrera 4S Coupè 3.8i (355 Hp) "GT CUP / GT3" '05 -> '08

The Supersprint exhaust system for the 2004-2008 PORSCHE 997 Carrera S / Carrera 4S is the ideal complement to 911 models equipped with the the last iteration of the  N/A flat six engine, in its most refined developement step, before the change to the Direct fuel injection system.

The 3.8L (355 hp) motor has room to spare for improvements in the midrange torque and in peak hp, which unfortunately are spoiled by the poorly designed stock headers, and by the restrictive nature of the standard, mass produced catalysts.

We at Supersprint have developed a prefect exhaust, with Race inspired, tubular headers, large-volume HJS Motorsport catalytics and free-flowing inner design rear mufflers.

The final results of the full system install are simply great, in terms of  performance and sound.

We offer our exhaust in multiple options, from Touring / Sport to full Race.

Thanks to the modular design, the rear mufflers can also be used as a cat-back only option, accepting the std/oem tail pipes as well.

An exclusive, limited edition CUP system with central-exit twin endpipes  is also available for the conversion to the GT3 style bumper, which boosts the mid and top end  hp even further; this is the ideal exhaust setup for racetrack use.

Systems for replacement of kat for OBD car models (with lambda sensors before and after the kat.)

These systems can only be used for racing purpose exclusively, in conjunction with the modifications of the engine management system. If used with a stock “ECU”, malfunctions may occur. All modifications must be carried out by qualified personnel only, under the liability of the car owner and at his expense.

Supersprint guarantee is limited to the quality, workmanship and correctly fitting to the intended car model for all race products.
