Can an Exhaust System be Clamped Together
Motor vehicle exhaust systems are all either welded or clamped into place. Each has its benefits and drawbacks; some parts will require one or the other.
Types of Exhaust
Auto exhaust systems typically come from the factory welded together. It is with the replacement of pipes, mufflers and catalytic converters that you will see clamps put into use, though some new cars will come with a combination of clamps and welding. The customization of exhaust systems will also result in frequent clamp use, as will older model vehicles mainly because they have had parts changed.
Benefits of Each
The benefits of welding are the complete seal and prevention of leakage that it provides. This reduces pollution and improves engine compression and possible rattle. Clamped exhaust systems make it far easier to replace parts when necessary and remove the cutting and welding elements from the equation.
Considerations
The drawback to welded exhaust systems, especially when it comes to replacement parts, is the potential for cracking should the weld not be done perfectly. The main drawbacks to clamping are the imperfect seals that are formed, the potential for loosening and the loss of compression and pollution into the air.
Combination Systems
Exhaust elements near to the engine including catalytic converter often require welding because of the high pressure exhaust they withstand due to their placement. Clamps tend to be used at the back end of the car.
