3, 5, 10 any odd cylinder sounds wierd, but you get an even number and thats when you get a decent sound. the ford v-10 sound strange to with exhaust. the only vehicle that doesnt is the viper. could it be the way the engines fires? wouldnt atleast 2 of the pistons hit at the same time reguardless?
There are some Triumph Speed Triples out there that do a dual but I don't really know anything about them much less pros vs. cons. But here's an example (not a dual) of a nifty sounding triple.
One thing i dont understand, is all the posts regarding 4-stroke exhaust tuning is predicated upon the idea that there is a period of time that both the intake and exhaust valves are open at the same time. I dont have the experience to know if this is true for only some engines, or true for all engines absolutely or not true at all. ________________________ ipad ebooks ipad comics
