The SITO systems are very accurate replicas of the standard exhaust systems.

SITO still offers many models for oldies for which original spare parts have not been available for a long time. Despite the lack of a Connecting Tube for exhaust gas recirculation, the Exhaust can also be used on Models with exhaust gas recirculation. Inner Tube and Intake Pipe must be completely removed and the secondary air filter box must be closed.
