EVO Header Systems |
Evo's uniquely designed stainless steel sport headers for the Carrera models is the work of many months of R&D, fabrication, testing and retesting. Our 100% bolt and emmissions legal headers are properly designed for the volumetric efficiency of the Carrera engine. Our equal length, long primary tube design offers better exhaust scavenging for more power and torque. Our headers will add more power as compared to the OEM headers and most all aftermarket headers, guaranteed!

| Evolution Motorsports K16 Sport stainless steel headers have been designed to increase HP and TQ on cars fitted with the OEM K16 turbochargers. The short design is perfectly matched for the exhaust travel from the heads to the K16 turbo for better boost response and power throughout the rev range. The smooth flow through the mandrel bends and pyramid merge collector offer superior flow characteristics as compared to the OEM headers. Power gains are increased by 14 HP and 16 Ft. TQ with no other modifications. |

| Evolution Motorsports K24 Sport stainless steel headers have been designed to increase HP and TQ on cars fitted with upgraded K24 and EVO GT640/700 turbochargers. The medium length and 41.5 mm primary tube diameter design is perfectly matched for the exhaust travel from the heads to the larger turbochargers for better boost response and power throughout the rev range. The smooth flow through the mandrel bends and pyramid merge collector offer superior flow characteristics as compared to the OEM headers. Power gains are increased by 17 HP and 20 Ft. TQ with no other modifications. |

| Evolution Motorsports GT Sport stainless steel headers have been designed to increase HP and TQ on cars making 700+ HP. We also install them on race cars making 650-700 HP. The large radius 44.5 mm primary tube diameter design is perfectly matched for the exhaust travel from the heads to the larger turbochargers for better boost response and power throughout the rev range. The smooth flow through the mandrel bends and pyramid merge collector offer superior flow characteristics as compared to the OEM headers. The larger diameter primary tubes are designed to increase exhaust volume to the turbos while reducing exhaust gas temperatures (EGT's) to safe levels on high power applications. Power gains are increased up to 30+ HP and 30+ Ft. TQ and EGT's are lowered by 50 degrees C as compared to the OEM headers. These headers are included in our GT750/800 tuning systems and are an option for the GT700R. |

Wastegate Boost Kit |
This pair of bolt-on 1.0 bar wastegate actuators provides better boost response and increased power. Evo's OEM quality higher pressure actuators are designed for cars that are generating higher than stock boost levels. The OEM wastegate actuators are set at .7 bar (10.29 PSI) of pressure, which is too low for modified cars. - Better boost response / peak boost holding pressure
- Less boost loss under initial acceleration
- Better boost recovery in between shifts
- A must for any 996TT running higher than stock boost levels
