Long before there were catalytic converters to keep an engine’s exhaust cleaner, there were smog pumps on engines. And stock smog pumps went out faster that an eight-year-old on Halloween night. If you ever changed your stock exhaust manifold for a set of headers, then the stock smog pump did you no good any way. If you have a GM, Ford or MOPAR engine under your hood and if you have already installed a set of Hedman Hedders, then there is probably a Hedman Smog Pump Kit designed just for you and your pride and joy. Every state has emissions testing and you want to be sure that your car or truck passes. To install a Hedman Smog Pump Kit onto your Hedman Hedders all you need to do is simply drill each primary tube, insert the air pollution manifold, weld it secure and then place all the hoses that are included in the kit to the factory air control pollution system. Hedman has been the leader in exhaust system components for over 50 years. All of their products mean quality, durability and reliability. Maybe that is why Hedman is the name professional mechanics choose when they install exhaust systems.
