2009 HONDA CRF450 EXHAUST
window to avoid weather variables). We sound tested each exhaust system (using the new 2009 AMA/FIM sound standards). And we bloodied our knuckles by installing and removing the CRF450 exhaust systems over 60 times during the testing period. During the course of our testing, we discovered that the needs and demands of different skill levels sought different powerbands. The favorite pipe of the Pro test riders wasn’t always the first choice of the Novices, while the Vet racers seemed to seek the middle ground. Thus, you have to have an inner dialogue with yourself about what you really want out of an aftermarket exhaust. These are our caveats: We tested the exhaust systems as they were sent to us. We didn’t add inserts to make the pipes quieter (and they all can be made to meet the AMA standards with inserts). We didn’t put more hours on one pipe than another before sound testing them. We never let test riders talk to each other during test sessions and, in fact, we conducted most of the round- robin tests with one rider at a time. We didn’t weigh the pipes (they are all lighter than stock and, as a rule, titani- um pipes are lighter than the stainless steel pipes). These are our results.
