GM Passenger Car with 305-350 Cu. Will not fit angle plug heads. Requires head pipe fabrication to Y-pipe. Includes O2 (Oxygen Sensor) fittings.Will not fit with A. Will not fit vehicles originally equipped with any engine other than Small Block Chevy. Finish: Triple Process Chrome Plated. Tube Outside Diameter: 1 1/2. Due to a revised chroming process brought on by recent EPA regulations and high labor costs, today's chrome is not the quality of days gone by. Be Aware: Exhaust components which are chrome plated are now much more susceptible to blueing, blistering, peeling & corrosion. We see very few headers that do not change color once exhaust temperatures are achieved. Please refer to the header measurement chart below to make sure the header will fit your vehicle and application before ordering.
Use care when trial fitting headers. Repack them well to prevent damage returning them to us.
