15020729  -  Exhaust Donut Seal/Gasket

I've had similar questions to those previously asked by others, you're answers are helpful. Thank you - I'm ordering a pair. Can you give a simple description of the "brace" you suggest? Do the downpipes brace to a chassis component, or to each other? ( Ricky Hunkins, 01/21/2024 )

Hi Ricky,

        When I have installed those braces, I just use a length of 3/4" square steel tubing, and two 3" exhaust clamps. Clamp them onto the pipe with the treaded ends facing each other and then weld the square tube to the saddle of the clamps. Doing it this way allows you to remove the brace when needed. This brace can be installed anywhere on the downpipes fairly close to the junction for the catalytic converters.

Will this fit my vehicle ( Caleb Coulson, 03/02/2023 )
Hello Caleb, we do not have a way to verify that as our VIN search only covers Workhorse chassis. You will need to verify the part # with a GM parts department .  ( Support )
HELLO,
I HAVE A WORKHORSE W22 8.1L , IS THIS THE CORECT EXHAUST DONUT? IS IT HEAVY DUTY OEM, I HAVE TRIED SEVERAL AFTERMARKET ONES AND THEY DON'T FIT TIGHT AND BURN OUT
THANKS BOB
( ROBERT MCCORD, 07/28/2019 )

Robert,

    That is the correct seal for your VIN. This is the exact fit replacement not aftermarket, you should have better luck with fitment if you order this part. We install a brace between the pipes in front of the flanges where the downpipe connects to the catalytic convertors. This prevents the pipes from moving and wearing on the seal.

I bought your seal verified by Jon. Now I forgot if the metal donut extension goes toward the engine or toward the muffler within the pipe. I am having lineup problems. Your new stud bolts barely have enough thread to get started. I put metal extension into exhaust pipe. Donut assy is too thick. Looking to verify that metal seal extension mounts into exhaust pipe
If so, I will free up exhaust pipe supports for best alignment and try to fit donut seal again. Your new stud bolts are about 1/4 inch shorter than old ones but old nuts threaded on far enough so these new ones should work. New donut is thicker than old one.HELP!

The flange installs towards the exhaust manifold. ( Support )
I need the donut gaskets for the exhaust manifold to the pipe. Is this the correct one? The part no. is 10520729 ( Don Warren, 09/12/2016 )

Don,

Yes the part# for the "donut" gaskets is 15020729
