Anyone cross reference the Magnum 325 etc donut seal to an auto part??

Polaris #5243517

Been googling all morning and haven't found anything. Waiting for a part to arrive from eBay just won't do.

Walker makes a variety of sizes and I can't even find the dimensions of the factory part. ID, OD, height?

I am almost ready to use exhaust cement, which I may have to if the flange is warped, but, would rather put a new seal in first.

 

If you still have part of the old donut left,measure the inside dimension and see if Autozone,O'reillys,Napa,etc can get you close.https://www.napaonline.com/en/p/EXT31360

 

Have not removed it yet!

Have learned my lesson over the years, don't tear the old one out until you have the new one ready to go!

Just in case you don't find it!

 

Donuts don't usually crumble if you pry them off. I've replace dozens of these over the years.That'd would be the fastest way to take one in and match it up. Whether it's an 1 3/8, 1 1/2,1 3/4 id don't know,never measured,but this could get you going rather than waiting on amazon,ebay.If you can't find one,slide it back on use some rtv until you got the right one in.
