Aftermarket pipes

How munch do aftermarket exhaust pipes ( e.g. S3 ) change the character of the machine? Are there any experiences with this?

In the past I have had long and short S3 front pipes on GasGas motors  and experimented with different set ups  and  the length of a piece of tubing makes a difference to the way the motor behaves but not massively on their own as other tweeks need to be done like carbs and such too make a really noticeable difference. If you are expecting one without making other mods to make a radical difference you would probably be a little underwhelmed and  the only way you will know is if you buy one and fit it to your own bike . Weight saving used to be the main reason to fit one when they first became available. As with everything its a case of how much money have you got to splash about. . They make more of a difference than reed petals do in my opinion to make some kind of comparison.

Riding partner ran one on Beta, reason for the aftermarket alternative was cost saving saving after a crash damaged the original system, sounded different more throaty (lower tone) and altered the power band slightly not to his liking but it was plenty lightweight and the fit was good.  It's not something that will make you win trials events or ride any bigger stuff, like say; new tires, wheel bearings, new fork consumables and a year supply of race fuel might.
