Hi all,

Exhaust systems on bikes are actually a very grey area. Everyone has his own opinion about gains made. When looking at the graphs supplied by these manufacturers it is very difficult to compare actual results. All use different correction factors and other fudge factors in order to have nice looking graphs, not to mention the smoothing of the curves.

Are there any sources that can be trusted that can supply realistic results that can be compared in order to make an informed decision.

Cheers
