Exhausts, standard and high performance

Exhausts, standard and high performance?

Whats the difference....apart from the price, i presume that they arnt just tubes of metal!

[Frost]

They are hollow tubes of metal with specially designed width's, lengths and with baffles inside. The amount and type of baffleing combined with the can dimensions effect how freely the gasses can escape.
Generally a 'Sports' exaust has far less baffleing and gives improved performace.
An after market end can is normally the cheapest, quickest way of getting more power out of your bike, allthough the extra power gained varies from bike to bike.

Also, with 2 stroke exhausts, the way the expansion chamber is designed can determine how the power is produced, i.e. more torque or more top end power. Baffles in a 2 stroke race can also have to be specially designed to keep in backpressure, yet at the same time flow as much gas out as possible.
