If you feed them into a pipe, you lose much of the scavenging effect. Length around 26 inches from the exhaust valve and either:
* end the exhaust system
or
* feed them into a large chamber (a resonator or freeflow muffler, not a hot-dog muffler) - then if you wish, a pipe can exit to the rear of the chassis
The exact length needed depends on your engine build, state of tuning, and racing conditions. Using the paint or lipstick is one method of letting the engine tell you the length it wants.
