You'll never find one on my cars. It's your engine, do what you will with it.

ok ok, i stand corrected. but what about this. some guy at my track actually cut his pipe's(the metal one) stinger down. why did he do this? more rpm maybe?

so, shortening the stinger will (theoretically) skew the powerband in-favor of higher engine speed (rpm). you'd have flat powerband when at lower rpm, steep spike on the "on" spot. good for people that tend to squish the throttle more (hardly let go and brake)
longer stinger might fit the "butter finger" better, since it has peak power in lower (than normal) rpm. average driver will feel this kind of pipe as "wild on turns, and less speed on straights). I prefer this setup myself, since it's a lot easier to pass a guy in the turns rather than the straights (the one w/ more control and "feel" will win), on the straights, it's just the matter of how high you can go (speed) and how long is the straight (relates closely as well to how quick you achieve top speed).
oh, one other thing, cutting your stinger shorter than 1,5 cm will be deemed illegal on most big/organised/international races, but if your track allows anything I'd say, go with the biggest stinger diameter you can find, and play with the length (STS sells a pipe w/ replaceable stinger to suit your preference in its length), or make your own pipe, so you can ultimately decide what, where, and how (just like me )

how do you make your own pipe? any special metals or welding techniques?
