To replace the exhaust of the Derbi Terra 125, you will need to loosen the screws that hold it in place on the appropriate supports, on the right side of the bike near the rear fender: once the support screws have been removed, you can proceed by widening the connecting clamp between the exhaust and the collector. In this way, the old exhaust tip can be removed to allow the new one to be inserted: the latter can now be secured with the appropriate screws and connected to the collector to check that everything is functioning.
