Default Welding exhaust

Pulled the rear Y pipe off and welded it back together. Had almost a 75% crack around the split. I know that I've heard that it's a design flaw and it will crack again.

How long do I got to find a replacement exhaust?

Found an air cleaner cover that doesn't rattle in my parts stash.

I had a guy do some tig welding for me. In his estimation cracks occur due to stress more so than vibration.

He was very careful when he did a header pipe for me to ensure everything fitted correctly before committing to the welding.

By you fixing it you can get the exhaust to fit perfectly to make a better exhaust than the MoCo, IMO.

My 1989 ElectraGlide cracked there. The welder rewelded it and added two gussets. Two triangle pieces added (top and bottom). I believe I had to trim the chrome shields back some because of the top gusset.

I was pretty careful when I mounted everything up. I don't think it's stressed, I guess we'll see

I believe it's a common thing. Before I welded mine I looked online for a set and every set of stock headers I found had the same crack in the same place.

That style pipe it's common even through the twinkies years, I've help redo several, even did one on the job for a coworkers bike that let go completely pulling into the parking lot, he had a 130 mi. a day round trip commute.

Check all the iso mounts particularly the rear on for that side, they get old, harden up and crack.
