Some ”sound” advice:- as many of our systems are of a more “free-flow” nature when compared to an original system, your engine may run leaner (ie. the fuel mixture may be weaker) and hence operate at a higher temperature. In our experience, the bigger the baffle » the less the back-pressure » the freer the flow of the exhaust gases » the hotter it will run! This is true of all exhaust systems and not just Stainless Steel systems! A Stainless Steel exhaust system in itself will not cause an engine to run hotter, despite various urban legends that claim this to be so. Stainless Steel does retain heat more than mild steel does (i.e. mild steel dissipates heat more effectively than does Stainless Steel), which leads to this misunderstanding. In fact, many newer-generation motorcycles (especially sport bikes) have at least the header-pipes in Stainless Steel as standard fitment.
Because of the possibility of the fuel mixture being too lean, we strongly recommend that the CO˛ level of your bike is checked by a reputable dealer and, if necessary, suitable adjustments are made to the fuelling of the engine to compensate. Testing under load on a dyno is the best way. Excessively lean running can, over time, lead to overheating of, and cause damage to, the exhaust valves and valve seats. It is also the single main cause of excessive discolouration of the exhaust!
We are very proud of our products! Should you require further information or clarification of the abovementioned points, please feel free to contact us at your convenience (details above).
