Now that you mention that.On the standard can it has like a sealant tape of sorts on the connecting tail that connects to the headers.Looks like the old muffler bandage stuff.The Yoshi didn't come with any and i never really thought it would need it being such a straight through unit.(Basically a can with a bit of rolled mesh in it.)
I'll throw it back on and see how it goes.
Thanks for the help guys.Much appreciated
