In the past few years more and more vehicles in the powersports industy have been adopting increasingly advanced fuel injection systems that incorporate oxygen (lambda) sensors for refined engine and emission controls. On vehicles where an oxygen sensor is present as standard, HMF will develop and produce exhausts that also accomodate the transfer of the oxygen sensor to the HMF exhaust system.
We've noted on some models, like those produced for European markets and other specific sub-models, will have an oxygen sensor was not present in the original vehicle that was tested at HMF. In cases like this, owners may need to purchase a bung and have it welded in to allow the vehilce to operate properly. HMF sells high quality, stainless steel bungs and caps that are compatible with all HMF exhaust systems.
