Exhaust repair is important for a number of reasons. Not the least of which would be the safety factor. Your exhaust works to divert harmful gasses away from you and those around you. That is why they are on the lower rear of your car, to minimise harmful gas exposure. A damaged exhaust can lead to those fumes causing serious respiratory problems and even death. Remember those people who commit suicide in a locked garage with the engine on? Yes, those fumes can be dangerous.
Aside from fumes, a damaged exhaust can lead to engine deterioration. See, the exhaust takes away all those gasses that could do harm to your engine. To work well, an engine needs a balance of fuel and oxygen. The exhaust diverts the production of the burning of these, but if it didn’t that careful balance would be thrown off. This can lead to parts of your engine working harder to compensate, leading to deterioration.
Fuel is expensive and everyone loves an engine that runs efficiently. Damage to the exhaust will mean that your fuel economy will dramatically decrease and this will increase your fuel bill.
