| This chrome exhaust tip is used for the 2" exhaust systems. This is the tip of choice for the first gen cars (70-78) that are using the 2" exhaust systems. For more info on why this is the tip to use go to our website at www.zspecialties.com, click on tech tips and then click on exhaust. Note: the 75-78 cars came stock with a 2" exhaust system. We recommend going up to a 2.25" or a 2.50" exhaust system for better flow. These tips must be welded on. For the 1979 and newer cars, a straight or angle cut tip is the tip to use.
