welding is always better. less failure points. but you can always just cut and use couplers. depends on the routing you take and the amount of couplers you have to how well that method will work for you.
also, get a chop saw! i got a cheapy one from harbor freight for $50 (normally $99 but often on sale). i couldnt tell you how many pipes from 2.5" to 4" it has cut. everything from alum to mild steel to stainless has been cut with no problems. heck we are still on our first disc even!
here is a pic of the first set of pipes made. used various mandrel bends, cut to fit, then welded together. it isnt hard, just takes time, patience, and more time.
