In my younger days I would just bolt some cheapo header mufflers on and drive it down to the exhaust shop

I bolted most of my exhaust on, used clamps and wire hangers and drove to the muffler shop too.

I had a complete JBA system (including H-pipe and headers) installed in my '66 GT Fastback and was told by the installer that the kit fit as well as any he had previously used. There were absolutely no fit issues, so I believe you should be able to easily get it installed and clamped together. I would at least have a muffler shop tack it if you intend to use the clamps permanently. I elected to have my system welded.

I had a budget of $1000 for my new exhaust system (headers back).  Unfortunately, I discovered this week that just towing the car to and from the muffler shop would cost my a ¼ of that.  So I ordered JBA 40-2653 and 1651ST pipes and will attempt to install it myself.  

 
The main challenge is that the tunnel pipes need to run close enough to the tunnel that they will sit above the subframe cross members.  I’ve gotten conflicting reports on whether or not a 2.5” system will fit tight enough in the stock position that they won’t interfere with the cross members.
My plan is to mount the everything from the muffler  back to get the correct placement through the rear valance and then install the mid H-Pipe up to the shortys and evaluate from there.  I'm crossing my fingers that should I need any adjustment it's something that can be taken care of with a ball joint adapter or something similar.  If not, I'll mock the tunnel pipes w/ PVC and have a mufler shop create them.  Last piece to getting the pony on the road gain!

 

 

Whats all that stuff?!!!

Make sure you get the car high enough to provide adequate space to maneuver around.  Working on my back was a real challenge trying to align, get clamps on, etc. etc.  This was one downfall of trying to do it myself.  Another is trying to do it myself, an extra set of hands would have been of great assistance.
In the past, I have also using cheap mufflers (glass pacs) to get me to the muffler shop.
My last installation, I purchased the mufflers first, put them in the car, drove to the muffler shop w/open headers, in a city location (about a 3 mile trip), figured if I got stopped I'd have a good excuse (in addition to my age!) to avoid a ticket.  All went well, did not get stopped, am very pleased with the 2.5" system that also calmed down (did not eliminate) my vibration issue.
