Ultimate Headers catted LTH - Cat failure and broken weld on mid pipe

Is the crack before or after the cat? If before, it probably was a good thing it cracked as it acted as a relief valve for the backpressure from the clogged cats. If this was the case, its a good design. Not an engineer but looking at it as a layman. If after, its poor manufacture.

I had the Vibrant Race Mufflers welded onto the Ultimate Headers mid-pipes today. I’ll try and install them tomorrow and hopefully get the car roadworthy again soon.
@WD Pro the welder carefully examined the aft sections of both mid-pipes and determined that the reason the passenger side broke was because it was fused (both sides of the pipe melted together instead of using filler rod). He welded them both up and and said they should be good to go now.

Ultimate price, mediocre mig welds.. - sorry, had too ha-ha.
At least the weld is solid now. Compliments to the chef !

You are right about the welds only in those areas on the mid-pipes. I can’t figure out why they didn’t add filler rod there. The welder/chef said he was certain that anyone else, who has Ultimate Headers mid-pipes that are fused together like that will eventually experience the same type of failure.

Why the mini mufflers? Are you looking to quell a certain kind of noise good sir?I had the Vibrant Race Mufflers welded onto the Ultimate Headers mid-pipes today. I’ll try and install them tomorrow and hopefully get the car roadworthy again soon.

I see.... I have a set of "race cats". Not sure how much they would help clean the air because I can see right through the honeycomb. You're doing the best thing though. Just get rid of them.
Engines cost a lot more than a few dollars nowadays. Let us know how those sound.
