So other than the flange needed for connection to the end of the "Y" pipe, why weld it? Most of the new exhaust systems use swaged pipes and clamps. I just helped a friend put a new MagnaFlow exhaust system on a 2016 Mustang GT and the entire system came with clamps from manufacturer. Any muffler shop can swage the pipe for not much money you will just need to plan for the locations and additional length to accommodate the swage fitting.

I have 3" of pipe plus flange that I cut of off an old factory cat and all of the holes line up just fine. The only angle that I am concerned about it the forward most 45 between the muffler and the Y pipe, on the muffler side. It should be a simple cut, rotate and weld but the weld part is what I will have to pay for. I will check out the clamps available locally for the 3" pipe, thanks.
The rearward 45 is to long on the muffler side. I am nervous about cutting to much until I have the car on the lift. I have the 82 Euro that might be more similar to the 79 if I need to pull the exhaust but really until I measure exactly where the headers end I am just guessing. Maybe Sat Richard will have it on the lift
Don't clamp it. Do it properly and have it welded. I never seen a factory exhaust that crush clamps their pipes. Aftermarket does it to make more money on the parts but it makes the exhaust system un-serviceable.
The exhaust is all boxed up and ready to be taken down on Saturday!!!<br/>
I think I have a welder lined up that may get to it next week. We have another event coming up Nov 5th......... It would be outstanding if I could drive it that day.

The Y-pipe 928 Motorsports is extremely well done.<br/>
Flared flange from stock cat.
The muffler was to large to fit in the cavity that holds the mid muffler so we had to move it to the rear. The 3" pipe that had been ordered from Jeggs was great but we needed an extra 45 angle. We found a local man that was able to bend the 48" that we had.
I am grateful to Richard @ Garage 928 for helping me bring this long term project to a conclusion.
Needing a 3" in and out limits me somewhat. We have about decided to leave the rear muffler on and find a small round one that can fit in one of the straight sections. This seems short enough (12") and has good reviews. Any longer and they get really quiet.
