Exhaust & Cooling System Fittings

Exhaust water bypass fittings increase engine performance by diverting water from the cylinder head to the bypass fitting, rather than forcing all of the water thru the exhaust system, thus drying out the exhaust. These machined bypass fittings are angled in 90 or 45 degrees and fit a 3/8" or 1/2" Hose.
