Each bike will obviously have its own unique sound. Trying to relate what the pipes will sound like on your bike is very hard to describe with text on a computer screen . Some of the links on our website have a sound file attached (denoted by a speaker icon) that you can click on and listen to. 

...STAINTUNE exhausts feature a removable sound restrictor in almost every muffler they produce (when the design allows). This restrictor allows you to adjust the sound levels to your liking. The photo below shows what the restrictor looks like in the muffler and also what the restrictor looks like when removed. You can see the little set screw on the underside. 

With the restrictor in place you will get an exhaust note that is just slightly louder than the stock muffler. It will be throatier under acceleration and deceleration and only the slightest bit louder under steady throttle setting like out on the highway. Think of it as a shotgun choke which reduces the diameter of the exhaust exit. It has only a very small effect on performance when installed. Its main funtion is to reduce the exhaust note to a very pleasing level. STAINTUNE pipes are actually one of the quietest aftermarket pipes you can buy. Even with the sound restrictors removed, they still come in a few decibles less than all other aftermarkets pipes. The restrictor is removed by removing 6 mm allen screw on the underside of the exhaust spigot. You then extract it with a pair of pliers.

With the restrictor removed you are now in full "Sport-Pipe" mode and the bike will be louder under all conditions (idle, acceleration and deceleration). A better way to put this whole picture in perspective is to determine how well you like your neighbours. With the restrictors in place you can attend the summer parties down the street. With the restrictors removed you can pretty much count on not getting an invitation in the mail.
