Where should exhaust clamps be placed? Unless you have to replace the entire exhaust system, only a few hand tools and standard parts are needed to complete the basic maintenance of the vehicle exhaust system. But what is the part that meets the standard? There are a variety of different components in the exhaust system. In most cases, large parts such as exhaust mufflers, exhaust pipes and catalytic converters need to be cut and welded, so you may not be able to solve them yourself. These main components are not part of the regular maintenance plan, which includes exhaust pads, exhaust clamos and exhaust racks.
