Maybe some of the blathering I do about exhaust velocity and backpressure will make more sense....

Cool write up.

Got to love sonic and thermal pulses. It does help to know about them when choosing an exhaust.

Thanks Dave, i did'nt understand a lot of it but i'm dumping my drag pipes and puttin some V&H straight shots on it.

Everybody tells me to git rid of them. I pulled a plug yesterday and it was black, when i git the money i will take it for a dyno-tune.
