Exhaust tuned length

[J1MS]

I'm enjoying this thread.

I think the answer everyone is looking for is 42.....







Or was that from the Hitch Hiker's Guide to the Galaxy.

okay, so i've not made an exhaust before and nor do i plan to..... but.....

What factors are the ones that would alter the length of a pipe?
What factors are the ones that would alter the diameter??



Theres some massive bodied exhausts out there now (phat mamber etc).

I always presumed that a larger diameter was important if say i had an extra transfer welded on top of my casing (lower primary)???

As over the same period of time (length) the exhaust could shift more volume??


I understand that there are may factors that can alter, but just looking at p/c???

anyone?
