Free-flowing Long-tube race competition headers without catalytic converters. Designed for maximum power and exhaust flow for race and track applications. Fabspeed Motorsport designed and engineered these Race Quality headers in 2004 when we bought a Boxster. Over 16 years of continual refinement and Dyno development has enhanced our design. Beware of cheap copies that are not back-purged or clones of the Genuine Article.
INSTALLATION NOTE: To ensure proper header seal, after initial heat cycle, tighten all exhaust bolts to the OEM torque specs.
