Paul,

	I'm not sure if the 90Q20V is identical to the 5KCSTQ, but on the 
5KCSTQ, that donut just ahead of the cat is indeed special.   Its a 
dealer only part I think, and it will work much longer than the 
aftermarket generic donuts from the local Muffler Man.  I tried one last 
winter just before I did the 3" system, and it lasted about 2 weeks.
