As critical as this Exhaust Systems are, its the most overlooked, commonly just pieced together with no method of operation and it can be the difference between power being lost or gained depending on the application. In this day and age you have the ability to have it all, all the sound, all the performance and all the comfortability configured into one system and In this video we will reveal the truths and falsehoods, myths and methodologies behind building the perfect exhaust for your vehicle

While the systems are not technically and mechanically identical - they operate on the same principles in similar ways.....
A tuned length straight pipe exhaust, is (kind of) identical to a pulse jet.
And setting up tuned exhausts to offer optimum performance at a specific area of the engines revolution range, and road speed, means you get a deeper vacuum at the exhaust port, when the exhaust valve opens, more exhaust gas is extracted from the cylinder, so more fresh air and fuel goes into the cylinder - and then out the exhaust, and the reflected pressure wave coming back from the end of the exhaust pipe, rams that unburned mixture back into the cylinder, before the exhaust valve closes...
Assuming that you do almost all of your travelling at 100 Kmh - in top gear, you can concentrate your most power at 100 Kmh, and the power band, starts to kick in at 80 Kmh - peaks at 100 - and fades out at 120 Kmh.
This is optimum tuning for long distance running... probably adding some 30% more power, when the throttle is opened wide at 90 - 110 Kmh...
But it makes for a breezy cruising speed at 100 Kmh.
