No such thing as a stupid question. Anyway, if the lake pipes are hooked up (a lot of them are just for show) they hook into the normal exhaust a head of the mufflers. With the caps on they don't flow. The idea is to take the caps off and do away with backpressure when racing, etc. Now adays the high performance muffler flows as good as open exhaust so must lake pipes you see aren't even hooked into the exhaust.
