Multi Pipe Days

[Powaton]

I need a technical/historical lesson to satisfy my curiosity.

I'm browsing Craigslist for fun and see lots old triple triples. Got me thinking, multi pipe setups used to be the ticket to big HP, even on twins.

Today we get all the power with single pipe setups. What changed? Pipe science and knowledge just got better?

Twins are out there , not many I know of two guys that have made them, both were hand made,no stamps.made real good power

I have made many more that i would like for twins and tripples in past and in the mid 90s I did some comparisons with factory sets of twin pipes and single pipe on twin polaris 600s and 800s and for Drag racing the twins on the mid 90s and 2000s did make more power and they were very rpm selective and not broad power range so not great for riding where you were in and out of the throttle like we have to be to ride in the backcountry. So. I think the manufacturers like SLP and others were up front and told those dealers or customers these facts.
