![]() ![]() Repairing your exhaust system starts with identifying where the problem is. Some of the repairs on your exhaust system can be done yourself, while others should be left up to a professional. Your vehicle’s exhaust system lives a tough life so at some point in the life of your vehicle it will likely need to be replaced or repaired. Lastly, your exhaust system runs along the bottom of your vehicle so it is exposed to all of the elements from road dust and debris to rain, salt, snow, and ice. This water often exits your exhaust in vapor form but on cold days or short drives, the inside of your exhaust system can be left wet, which causes the metal pipes and components to rust. Also, one of the byproducts of good combustion in your vehicle’s engine is water. The extreme temperature swings – from ambient temperature to possibly over 1200 degrees – cause a lot of stress on all of these components. To accomplish this your exhaust system uses a variety of manifolds, heat shields, pipes, joints, flexible unions, mufflers, and rubber hangers. So your exhaust has to safely carry dangerous fumes quickly and quietly to the back of your car without getting anything too hot. Lastly, your engine vibrates and moves around quite a bit while you are driving depending on whether you are accelerating heavily, downshifting or just idling. ![]() The complications come in when you look at the route that your exhaust will have to take and keep in mind that it can get to be extremely hot. Your exhaust system’s secondary purpose is to muffle the sound of the explosions that are happening inside your engine as well as the sound of high-velocity gases escaping from your tailpipe. #Manifold exhaust windows#The safest place is somewhere outside of your vehicle, far from you and any windows or openings in your vehicle which usually means somewhere under your rear bumper. The primary goal of your vehicle’s exhaust system is to direct the gases coming from your combustion chamber to a safe place. Your vehicle’s exhaust system serves a relatively simple purpose but sometimes accomplishes it in a complicated way. ![]() In this article, we will talk about your vehicle’s exhaust system, symptoms of a leak and what you can do about. You’ll also need to decide whether your car warrants a more expensive steel manifold or one made from iron - your decision will depend on your budget, the age of your car and whether it’s a performance model or a daily runabout.Exhaust leaks can range from very serious problems to an issue that seems to make your car or truck sound really cool and go faster. Looking for a new manifold? Your choice includes OEM parts, aftermarket manifolds and even used manifolds salvaged from other cars. Some manifolds are also coated with ceramic for insulation, which is expensive, or exhaust wrap, which is cheap - but the latter shortens the manifold’s life. It’s important to get these issues fixed as soon as possible, because as well being an annoyance, the engine’s performance will be affected.Īn exhaust manifold gets very hot so most are fitted with a heat shield to protect other components under the bonnet. The manifold gasket, which sits between the engine and the manifold, can also fail, resulting in a similar amount of noise. #Manifold exhaust manual#
