Some vehicles may have a more complicated process for repairs of this nature than others do. While this is a fairly simple repair to perform, it does take some tools that not every may have. Taking too long to fix it can mean a much higher repair bill than if you took care of the problem right away. If your exhaust manifold starts to leak, it can cause severe damage to your car. Different garages will also have their own hourly rate for labor, but the average you can expect to pay at some of the major chains is below. Some manufacturers charge more for the parts than others, which can cause the price to fluctuate. The cost of having an exhaust leak repaired will vary depending on the type of car you drive. If you get the work done at your dealership, you can expect to pay more, but you may also get better quality parts and service. While different vehicles require parts of differing prices, the range is somewhere between $15 and $50. The parts aren’t going to cost much either. Expect to pay anywhere from $125-$300 for labor costs. It just depends on how difficult it is to get to the exhaust manifold. In some cars, it may take a lot less time, while others are going to take more. Exhaust leak repair should take anywhere from two to three hours to complete.
