Show original supplier description
The Nissan 15-6314 is a performance exhaust system engineered specifically for 1984-1989 Nissan 300ZX (Z31) coupe models to reduce back pressure and improve flow. The system utilizes 3-inch aluminized steel tubing from the catalytic converter back and includes a polished stainless steel Sebring Spiro-Core muffler paired with a 4 1/2-inch polished stainless steel tip. The system is compatible only with 2-seater (coupe) models. 2+2 (4-seater) models are not compatible with the standard kit and require a separate extension pipe (part 15-6067) to ensure proper fitment. The kit does not include a catalytic converter, converter gasket, or the headpipe forward of the converter. Installation requires specific attention to the rear hanger assembly. Because the kit replaces the lower portion of the factory rear exhaust hanger, standard OEM replacement bushings will not fit this location. Users installing this system should source the appropriate 15-8064 hanger bushings for the rear muffler position and 15-8063 bushings for the middle rear hanger assembly. All necessary clamps and hardware for coupe models are included.
