AFI Turbo External Wastegate Headers Porsche 996TT 01-05 description
AFI Turbo has released their all new made in the USA stainless steel high flow headers for Tial 44mm External Wastegates. Engineered and designed to fit all 01-05 Porsche 996TT cars. The headers feature CNC machined 1/2 inch thick flanges with a "true merged" collector. V-Band clamp flanges are welded on the header and included dump tube for a clean and easy installation. The Wastegate tube is placed just off the side where proper exhaust flow will activate the Tial Wastegate without any boost creep. The headers are made from 8gauge 304 stainless steel. These headers fit stock style turbo configurations including: K16, K24, and other hybrid turbos. The turbos fit to the headers using factory hardware and gaskets. The kit includes hardware to block off and keep closed your factory internal actuator flap. As tested by Vivid Racing on a K16 turbo car, these headers made approximately 40 ft/lbs of torque more then the stock style internal wastegates. By bypassing the exhaust system and dumping the exhaust gas straight out of the headers, a large amount of power is picked up. Note: The factory boost solenoid cannot control external wastegates. You will need a boost controller or you can run the wastegate spring boost of about 1.0 bar. Tial Wastegates are supplied with .8bar springs.
