Can I get some ideas here on this?
Not the best pictures but hopefully someone knows what this is

Found it on the bottom of the drive behind the thrust washer
Some sort of bushing? or rubber spacer?

exaust flapper valve bushing, used to hold the flapper in the y pipe.

Well hell if that is all it is!
Guess its safe to assume I could do away with it?
Going to look up on the microfilm to see if I can find it

thanks

anyone have an online drawing or scan of the Y-pipe assembly?
Cannot find it on Bam's site

Gotta know where to look.

Problem is, the pic is of the old style, which is no longer availible. I'm sure the part number is superceded to the new all 1 peice design. The square bushing is for the newer y-pipe that are slotted vs have a hole for the bushing.

That'll work too.

thanks guys!
Bam, guess I need to learn your site better

Now that I see this I Think I need to tear into it to get the remainder of the flapper assembly out of there?
This is not my primary exhaust route so i know its not a complete blockage.
But at times I do close the tips and use this route with more pressure

At least I am thankfull that it is not a DRIVE peice
