Just picked up my new Walker 55544 muffler and with it a Walker 36454 installation hardware kit for the connection between the tail pipe and the muffler.

This joint has two flanges held together by bolts with springs over them to allow a little flexing. The springs are tightened almost all the way, so there is barely enough room to stick a credit card in between the coils.

The new Walker one has two bolts, two cupped washers, two springs, and two spacers that seem to go inside the springs. There are no instructions to show how the cupped washers go. It doesn't seem it would matter much, but since they bothered to supply cupped washers instead of plain ones it seems there must be reason.

The spacers allow the springs to be compressed when tightened no more than 1/8" from their uncompressed length. This barely compresses them, leaving an almost 3/16" gap between the coils. This just doesn't seem like enough pressure to do the job that the almost-coil-bound Toyota springs were doing. It's tempting to throw away the spacers, and set up the connection like it was with the Toyota parts with just bolts and springs, so it can be really tightened, but the bolts have limited threading, as if they are made to be used specifically with the spacers.

Any thoughts on how to set this up?

One thing you will learn if you turn enough wrenches is that direct replacement aftermarket parts rarely are the exact same as what they replace...I keep an assortment of washers,spacers and nuts on hand to complete installations when needed....put it together how you think it should be and if it leaks then modify your work.....you may need to cut or trim the spacer to make it short enough to get the compression you need (spacer keeps the spring from bowing out)...also the washer probably goes with the cupped part over the spring so that the spring stays centered as you tighten...
