All 3 I replaced had the end cap weld break. That part of the muffler did not anything to do with the local shop who installed the brackets to the core. The cores are Chinese CRAP.
Muffler failure catastrophic

I hate to say it but I will the exhaust is crap made from China! I just don’t like it. If I didn’t have several other issues come up this fall I would of already bought the welter! Alpha was good to me for the replacement. So I can’t complain about the customer service from them.

It really sucks, they trusted a local shop to make them and the shop did a shitty job with "cheap parts" .
-
This exhaust and the variable are a current source of headache for them, allegedly(according to another local rider) the shop who sells the mufflers to alpha has refused to acknowledge that they are defective leaving alpha to eat the whole thing themselves, a rather sour pill to swallow if you ask me.
Didn't know that part. I have the variable. Already had to fix it once, but it was an issue with the flapper, vice body rattle. Guess I'll keep an ear out for that.

My wife's has about 5K on it and it seems to be holding up fine.

I will give it away when I get a new one but I couldn’t sell it to a forum member.

i have had mine for 3 years now, just went out and checked after reading this. sonofaB!!#! It is cracking but not separated. Anyone get theirs re-welded? I really don't want to buy a whole new system.

Tried to get mine rewelded. Really good welder said “No”. Said “too much time was spent polishing to make it look pretty and too little metal was left to work with”.

well crap, I am going to check around for the hell of it but thanks for the info. I will pull it off and pimp it around for a taker, or science project.

If it was me and I didn't want to spend money for a new one I would try JB Weld first. Maybe cause that's my initials.RNJ12

I have another one I’m not using that needs welded.
-
You might try using the inlet, outlet, and brace and have them welded onto another muffler. There are quite a few that are the right size.

Just out of curiosity does anyone have one that has held up? Mine is still intact with only a couple thousand miles on it.
9k miles and no issues. Of course now that I said that
. Guess I’ll keep an eye on it 
-
I honestly think the earlier ones have held up pretty good, but as the demand increased production quality went way down.

I had mine welded with no issue. It depends how much it is separating and the welder you find.
It can be done though. -
Mine broke around over half the weld. Original weld and area around it was polished down way to thin to reweld. Whoever ground the weld and polished it wanted it to be really smooth and shiny.

I will agree to a point. There is a level of ownership when sourcing product and then applying modifications. The slingshot is still relatively new and the aftermarket is honestly still finding what works and what doesn't. I will add that all parties are applying products outside of there original designed location (most SS products are adapted from other applications) and therefore must expect some failures. In my opinion the location of the muffler, regardless of the supplier, has to be factored in along with modifications. The loads being requested of the muffler where the cats have been deleted and then being located so close to the manifold amplifies the requirements past most standard designs. Now lets drop in a turbo or a S/C and things really start to multiple. Past the muffler housing itself all mounting points also need to be really beefed up because of vibration that is normally absorbed along a longer traditional exhaust system. I think collectively we should be expecting failures. Personally a large multiple chamber muffler designed similar to the OE both in size and exit point will be needed but at a great cost to the company first to market with it (AKA totally SS design from the start). I can tell you the OE gutted of the internal cat and additional pass through holes into each chamber greatly improved sound and performance. Now the test will be the S/C in the future.
Now these are opinions only. Please do not read anything else into this. We are all learning from our failures and making changes as we go. Yes it sucks but that's how development works.
This is why I still have not purchased an exhaust system yet.
