Also you may want to drill a drain hole for water at the low point in the system. Jim.

This is how I got the stainless tail pipe that sticks out polished.

I turned the tail pipe outward so it doesn't blow up as much dust. Made a noticeable difference in my unfinished driveway
Looks good. So how loud is the Jake brake with the resonator?

When I did my exhaust upgrade, I used two Jones' XLs inline.  It was either one XL and a steel pipe to do the job, or two stainless steel XLs for $10 more to make the connections to the tailpiece.  Of course, I have no comparisons about the sound.  Too many grenades and mines, and later jet engines for me to hear properly anyway.  So it all sounds good to me.  Wish I had converted years ago, just for the cooler bedroom and access to other things in the area where the muffler used to be.  And I will always thank my patient and practical youngest sister for wrapping the complete exhaust system and installing a turbo cover.

Coming up the hill east bound out of Albuquerque with some concrete wall on my side last Thursday and I could hear turbo whistle over the mellow bellow from the resonator, temp was near 100 so I was pulling about 2000 to 2100 rpm at about half throttle and in probably 4th gear all the way up with coolant temp at 190. There were a couple rigs on the shoulder that were probably trying to pull the hill flat on the floor.. little Cummins sounded sweet and was working very nicely for a small horse. The low tone noises of a rig pulling and working is worth every cent paid for the resonator for me.

That and a EGT gauge is all I had left to do to compleat my exhaust.
 I was actually surprised that is wasn't that much louder IMO but I do have 40 years around planes. Never heard anything in the tunnels that were noticeable. Probably don't need the egt but I do enjoy seeing what's going on and do like seeing a compleat cool down before shutdown. Now to build some additional storage for parts and 🧰 tool box.

I bought  the coach home this morning towing the Sidekick and 8 percent grade
4th gear in the traffic the Jake was almost holding so added a touch of retarder, 1st
stage. I kind of like the sound of the Jake and going down that grade I manually
shifted it down to 4th gear. I really like having the choice of how I use the Jake.
If I had to blow a hose I guess this was a good place. This is the first time towing
the toad with this coach. Don't even feel it.

It was the hydraulic hose out of the pump, maybe a 1 inch hose, used a
11/4 wrench.
