My thermostat failed on my MSX 140, the engine got hot but I shut it down in time before major engine damage, but there is major damage to the exhaust components, the plastic resonator and connecting hoses are all junk !!. No more thermostats for me folks !!

Does anybody who has done a conversion to pipes have the take off parts- resonator, large connector hoses, plastic extension from the manifold log ??? Looking to buy.
