I have the fmf Ti slip on pressently with the insert ring installed. It mellowed the low a tad helped the over rev some . Nothing special. Although it sounds Great if that matters. So I now have the mega bomb head pipe & mid on the way. It has plenty of power ,Just want to mod the delivery up top, to stretch gears out.We shall see. Although In good track conditions I actually dont mind the low end snap. This week I will start to try out some tuner settings.The fmf slip on is apx 1 # lighter than stock. jeff
