Normally popping or banging on overrun (when the throttle is closed) is
caused by an exhaust leak. Don't know the technical reason behind it
something to do with vacuum and air getting sucked in, the leak is normally
where the silencer joins the collector box. And it doesn't have to be enough
of a leak for you to notice exhaust gases coming out. We used to
deliberately loosen them as kids just to get this effect.

		 Hi there,
		 I'm a long time reader of that list, so thanks to the
writer's list.It's my
		 first mail over there.
		 I'm a @ RD04 proud owner. So I've got a little problem :
Few month ago i
		 noticed when 
		 decelerate some exhaust noise (a well known little bang).
My exhaust needed
		 to be changed, and 
		 my dealer said it was the cause of my issue. So i did it. 
		 My new open exhaust do the same noise :-(   but more lower.
		 Any idea ?   
		  >>
		 It could be the sealing (Dichtung) of the exhaust directly
where it's coming
		out of the motor (krümmer) ; I had the same problem , but  I
didn't change my
		exhaust just the sealing and all problems were gone.

		i hope i could help you
