I have a 99 Volvo 5.0GL. I removed my exhaust bellows and found a set of flapper valves mounted on a shaft inside each of the exhaust pipes below the elbows. One was melted and the other one has melted off and fallen down. I have looked on the volvo parts breakdowns and I cannot find the flapper valves. Anyone have any thoughts on this?

The flappers were eliminated, here is the service bulletin on their elimination.
