would a tuned pipe do my fox 46BB any good? what could i expect to gain? and if so, which one? how do you tune a tuned pipe? iv herd of people burning up a engine with a tuned pipe, why would this happen?
It all depends on what you're after. Any engine will show a power gain with a tuned exhaust system. Some more than others, depending on exhaust timing. First you have to pick your prop and/or RPM range. Then you have to decide what kind of pipe you want. Some pipes will "tune" (resonate) in a narrow RPM range. Others (broad band pipes) will "Tune" to a wider RPM range. The narrow band pipes will give you more power at the "tuned" RPM. Broad band pipes will give lesser power boost over a broader RPM range and are more flexible in terms of throttle settings.
So, what's your application?
