i have just replaced my standard taperd pipes with some 2006 standard slashcuts.They seem to pop a bit at about 3,oo revs ie just of tick over when you rev them is this the norm as the tapered ones dont, also seem to vibrate a bit more.has any body else noticed that the stahdard slashcuts pop cracle abit just of tick over and on the over run like the look of them better and want to stay standard
