sonett - adding union to MSS exhaust

I like the MSS exhaust but it is a really a pain in the butt to remove. Any time you want to pull the engine, the exhaust has to come down, and the only way that happens is if the left and right pipes are separated. The right pipe slips into a joint just before the Y connector. It is impossible to get the pipe back out of this slip fitting. This last time I was removing the engine (again) I got frustrated and simply cut the pipe. This make removal and installation MUCH faster, but even with an exhaust patch clamp it leaked like crazy.

Ultimlatey I purchased a 2" ball joint looking exhaust coupling. I really like this coupling. One end is rounded into a ball shape and the other end is made to receive that ball. Bolts go through a flange on either end and pull everything together. The end result is that you have pretty forgiving joint, you can come in at slightly bad angles and still have the ball type joint make a good seal.

The MSS exhaust is smaller than 2" (maybe 1-7/8" or something like that, I didn't measure). I expanded the MSS pipe to fit snug on the 2" ball joint adapter, which itself came expanded so the I.D was 2 inches.

I welded everything up with my MIG welder. Supposedly TIG is better for this job, but I have a MIG and have an acceptable skill level at it. Once everything was done, I sprayed the joints with some rust preventing primer. I am happy to report there are no leaks from the joint or the welds. The exhaust sounds great. I am very happy with this modification and I know I will appreciate it all over again every time I pull the engine out again.

I later spray painted the remaining bare metal side. No leaks, sounds great!
