PS. The other change I made when I got back into it was flanged connectors at the muffler. Its a lot easier to do service work if you can pull a few bolts and drop the exhaust.

If you don't add the flanges at the muffler, use plenty of antiseize on the slip fittings and don't overtighten the clamps. If the pipes get dented by excessive clamping, they are no fun to get apart.
