Porsche 987 Boxster/Cayman NHP Equal Length Exhaust Headers
IMPORTANT: Installing these Exhaust Headers will cause a "Check Engine Light" (C.E.L) due to not having catalytic converters. We do sell 02 sensor bungs to possibly reduce the chances of getting a C.E.L .
These NHP exhaust headers are meant for off-road use, in most states or provinces or even countries driving a car with no catalytic converters is not permitted.
