Geometry, exhaust system diagnostics in Israel.
Such signs as a sudden exhaust sound change, the presence of smell of exhaust gases inside the car, an exhaust pipe rattling noise or the significantly heated floor inside the car, indicate that the exhaust system must undergo diagnostics. In order to find a malfunction, an expert inspects the exhaust system, checks the exhaust system using a scanner, measures the CO level at different engine speeds, checks the temperature of the catalyst and resonator, as well as the pressure in the exhaust system.
