Gas van Gas van A gas van or gas wagon ( ("dushegubka"); ) was a vehicle reequipped as a mobile gas chamber. The vehicle had an air-tight compartment for the murdered victims, into which exhaust fumes were transmitted while the engine was running. The murdered victims were gassed with carbon monoxide, resulting in death by carbon monoxide poisoning and suffocation. The gas van was used by the Soviet secret police in 1930s. During World War II Nazi Germany used gas vans on a large scale as an extermination method to murder inmates of asylums, Romani people, Jews, and prisoners in occupied Poland,
Aftermarket exhaust parts engine. This is done by using an individual pipe for each exhaust port that has smoother bends with a larger turn radius, decreasing airflow resistance, as well as a calculated pipe diameter to obtain a good scavenging effect for the specific engine capacity. The pipes then merge into a collector and then flow into a larger pipe (down pipe), just before the catalytic converter. With equal length headers, as each exhaust valve in the head of the engine is opened and exhaust gas is forced out, it passes down one of the header pipes and through to the down pipe,
