Is anyone out there using the powerpros exhaust system?? looks very similar to the graydon proline (infact think they are the actual manufacturer for graydon) . What jetting would be suggested for this setup bike stock other than k&n in box .

 

have not seen it. do you have a link?

 

Power Pros

Although they do not have a link to the DS exhaust, I compared their other quads exhaust systems to those equivalents of graydon proline and they look identical. And don't forget the Grayodn proline exhaust for the DS is identical to that of CT racing.
