Exhaust Gaskets

I purchased a full aftermarket exhaust (midpipe and axleback) and need some good exhaust gaskets. Are the aftermarket and OE gaskets the same size for both the downpipes to midpipes (2 gaskets) and the midpipe to axleback gasket (1 gasket)? I have found links for downpipe to midpipe gaskets, but not for midpipe to axleback. Anyone know of the part number or have a link for a good aftermarket one?

It's been a couple years since i installed mine but i don't remember there being a gasket between the mid pipe and axle back sections. IIRC it just slips on and clamps.

The midpipe to axleback is what is called a "donut gasket" that is a fibrous gasket that fits on the OD of the midpipe flange and fits in the ID of the axleback.

OK I will be getting some downpipe gaskets that I found easily online. Do I need to purchase the donut gasket or can I re-use the OE one? You are referring to #11 in the diagram, correct?

I am pretty sure, assuming you can get the gasket off, it is reuseable. I dont have a P/N off hand however.

Edit: quick search on REALOEM found this PN:
02 Gasket ring 1 18117553130 $26.38

Ok I have the stock donut ring that I can re-use and I have new downpipe gaskets. Anything else I would need to attach the midpipe to axleback? Any new bolts/springs and such?

bolts and springs should be fine to reuse for the mid-to axleback. Not sure on the DP to mids though.
