hi had to change the standard exhaust downpipes because of a very loud rattle from the front exhaust valve ,is there another standard exhaust of another year of bike ok to fit and which model would be a sraight change cheers tricky
 
is this a common problem on the beemer rattle from standard front valve ?
 
yes, especially on cold start up.
hi r25sti this rattle vibration was happening cold and hot ,the front exhaust valve wear was checked with a long screwdriver press on the valve all noise went so that was confirmed to be the fault.are the 2015 gen 3 downpipes better?cheers tricky

Had mine swapped under warranty. 18 months later same issue with replacement ones. Saving pennies for a straight through Ti pipes.

I'd swear this has started on mine after an engine swap,
Where is the valve located? Only one I can see is at the rear box
