Does the exhaust affect gas?
If your car’s exhaust has a leak, this will have an impact on the pressure in the exhaust system, reducing fuel economy and leading to higher emissions. If a leak develops in the exhaust close to the engine, this can have a big impact on fuel economy, and could lead to fuel wastage.
What causes a burn on the exhaust pipe?
These burns are most commonly caused by exposed skin making contact with your motorcycle exhaust pipe, and by exposure to open flames or scalding liquid, like the coolant in your radiator. Symptoms associated with second-degree burns are the same symptoms associated with first-degree burns, but with more severe pain and possible blisters.
What are the symptoms of a bad exhaust pipe?
1. Excessively loud exhaust making hissing sounds. One of the first symptoms of a problem with the exhaust pipe is an excessively loud exhaust.
When do the gasses leave the exhaust pipe?
So the exhaust gasses leave rapidly early in the exhaust stroke. Also, when a pressure wave traveling in a pipe reaches the open end (or a chamber, like a cat converter or resonator) a rarefaction (negative pressure) wave is created and travels back in the other direction.
Can a burn valve be opened in an exhaust system?
noctrl July 4, 2016, 9:33pm #1 A number of times on the show it has been mentioned that an exhaust system without back pressure can lead to burned valves, notably the exhaust valve. I’ve talked to a few friends with auto experience and they agree this is the situation.

What causes the exhaust to burn in a lawn mower?
If a leaky or too-short exhaust pipe lets fresh air reach the exhaust valve it burns. The exhaust does not come out of the engine in a steady stream, it comes out in pulses. This is pretty obvious with a single cylinder engine, like on a lawnmower.
