Exhaust System Check

摘要

When your truck's exhaust system is running well, the truck is quieter, exhaust emissions are low, and the back pressure within the system is balanced. You don't want the muffler to put enough baffles in the exhaust flow so that it shuts down the sound, because it would also shut down the flow. If the flow becomes too high, the sound increases as well. Let the back pressure go too high, and the engine will stall because the fuel/air mixture is bottled up in the combustion chamber.
