How does one connect braid to the exhaust pipe and muffler? I presume the frame connection is with a bolt or screw after scraping paint off.

I used hose clamps on the exhaust pipe and look for a nearby bolt in the frame to connect it to.  I also use copper ribbon stock as braid takes a licking up here in salt country.  I cut a slit across the the stock that will allow the width of a hose clamp to pass thru it, wrap the stock around the pipe, feed the hose clamp thru the slit and around it and the pipe, and tighten.  If you haven't done so already, don't forget the doors, hood, and trunk lid or rear hatch.  I jumpered the hinge in two places for each.

To save wasted effort you will want to check for ignition noise as you add grounding straps. Stop adding them when the noise reaches a low enough level.

Rather than connect directly to the exhaust pipe and all the heating and cooling [expansion and contraction and oxidation] I used small hose clamps on the rods [1/2" dia] that connect exhaust to hanger.Make sure you scrape metal clean and use anti-oxidant goop.

If you use stainless steel hose clamps, you don't have to worry about expansion. Just use a star washer under the lug that's under the clamp, to assure a good connection. Leave a little slack in the ground strap as the exhaust system does move around.

I also attached to the support rods as AC2RC did except I tac-welded the braid instead of using a clamp, and tac-welded the other end to the frame.
