Abarth, exhaust system tuning in South District.
The exhaust system is tuned mainly in order to increase the strength of the engine, which can be achieved by installing a direct-flow muffler and removing the resonator. Moreover, the tuning involves polishing of the manifold valves, installing a manifold with tubes, increasing the diameter of the pipe, and removing the neutralizer. The exhaust system tuning is a complex technical task that requires special skills and appropriate tools.
