It typically consists of a series of pipes, a catalytic converter, a muffler, and a tailpipe. A well-maintained exhaust system is crucial for the overall performance and efficiency of the vehicle, as it helps reduce emissions and noise levels. Regular inspections and maintenance of the exhaust system are important to ensure it is functioning properly and to prevent any potential issues. **

Yes, a sports exhaust can change the exhaust emissions of a vehicle. Sports exhaust systems are designed to improve the flow of exhaust gases, which can result in a change in the emissions produced by the vehicle.
