crack on exhaust header
noticed a small crack on the rear cylinder header of my '07 Road King... already ordered a true dual pipe from Fullsac, any reason in the meantime I shouldn't be riding?

this is common.
easy to weld but DO NOT weld with it on the bike ( blow the ecm).
just take it off, take it in.
this crack may cause damage to the exhaust valve/valve seat, so don't ride a bunch until it's fixed even if temporary like some kinda fix-it stuff from pepboys.
the Y pipe can be stressed and cracked by owners hammering on the mufflers when changing slip ons.

I've had 2 crack at the y joint, at the bottom of the rear pipe. I think they crack do to the shake from the rubber hanger mounts. The header pipes are solidly mounted but you can jiggle the mufflers. After a while something cracks.,,
