Good for scavenging exhaust gas at certain RPM aint it? Due to high and low pressure waves and pulses. |

Forget it Jimo, It's not like you can do anything about the length anyway. I think Graham was saying either chop it half way up the car (something like 3ft length total no muffler) or run the exhaust at twice the length of the car. Either of which is useless

Hmmm, unless you make a long pipe that curves in an s shape under the car to get the length 
Good luck over speed humps ay! hehe Pete. |

Nope - S shapes only create swirls and resistance which defeats the purpose of the scavenging effect of the lengths. A cone shaped bit in the last exhaust section could help though as the gases expanding in the cone creates a vaccuum that is filled with the next pulse of gas. |
