Not all diesel vehicles have extra vents in their exhaust. But those with a larger engine, like the exhaust tips of trucks, have vents for safety reasons. The exhaust gas coming out of them is hotter than normal. The vents help them cool down and also let out some of the hot gas sideways rather than straight towards the rear of the vehicle. Sometimes people attach trailers to the rear end of pickups. If the hot exhaust gas was to hit the trailer constantly, things attached behind the vehicle would either burn or end up very damaged. These vents ensure that those things that are directly behind the vehicle for a long time do not get damaged.There is no better place to look for exhaust tips than online.
