I'm installing a GoWesty stainless steel muffler on my 1990 Vanagon. Do I need these muffler shims?

Yes, if you are using your original OEM muffler saddles with the GoWesty stainless steel muffler, you will need these aluminum shims. The GoWesty muffler has a slightly smaller diameter than the original, and these shims are designed to fill that gap, ensuring a snug and secure fit. You'll need two shims per vehicle.

When would I NOT need to buy the muffler saddle shim?

You won't need these specific shims if you're replacing your original OEM muffler saddles with GoWesty's dedicated stainless steel saddles. Those replacement saddles are designed to work directly with the GoWesty muffler without needing an extra shim.

How many of these muffler shims do I actually need for my Vanagon?

While they are sold individually, you will need two (2) muffler saddle shims per vehicle. This ensures that both sides of the muffler are properly supported when using original OEM saddles.

Are these shims compatible with 1986 Vanagon models?

Absolutely! These GoWesty muffler saddle shims are compatible with Vanagon models from 1986 all the way through 1991, provided you are using the original OEM muffler saddles when installing your GoWesty stainless steel muffler. They are a crucial part for a secure fit on those years.

Due to the slightly smaller diameter of our GoWesty stainless steel mufflers as compared to the OEM muffler, you will need a pair of our aluminum shims if you plan to re-use your original OEM muffler saddles. If you are planning on replacing your original muffler saddles with our stainless steel saddles, these shims are not required.

Sold individually. Two required per vehicle.

Fit note: To be clear, these shims are only required when an aftermarket GoWesty stainless muffler is mated to OEM VW muffler saddles.

New muffler straps

Kept my old saddles so this made the new muffler snug and not shake around. Gotta bend it with your hand a bit to make it fit.

The muffler saddle shims are very good!
What surprised me, was time it took for you give the shipment to the carrier. It showed several days as shipped but only the lable was created. The carrier was showing: waiting for the package. It is the second time that I have to wait so long for my parts and it was because of GoWesty taking so much time to hand over to the carrier.

Good fit

Fit as they should.

Muffler Shims worked for other mufflers

I ordered a Walker SS muffler (22485) and to fit it into the existing saddles, I bought two of these shims. Since the shims would not fit over the lip of the muffler, I sawed them in half and used one half for the bottom saddle, the second for under the top strap. The muffler seam fit through the gap in the shim on each side. The strap pulled them in tight.
