I am a quality control weld supervisor, and if I went to inspect that weld the person who made it would be looking for another job. |

Looks like the summer intern did that job. |

Did you use a steel or stainless steel bung? Maybe it's hard to weld a thick steel bung to a thin stainless pipe? |

Here's what I would do.
1. Buy new pipe and bungs
2. Get real welder to install bungs.
3. File a claim in Small Claims court.
4. Bring the ruined pipe to court, with all receipts for the original job, and the second one.
5. Chose mediation at the court, expect to get an award of half of your costs for the new pipe, the bungs and the welding.
Frankly, I would not put that work on my bike. It could be unsafe in my opinion, not to mention some serious ugly.
I don't like serious ugly.

If you think the outside looks bad, I'll bet the inside of the pipe looks a lot worse.
There's probably so many tonsils, weld drip and spatter in there that the exhaust flow is greatly restricted.
I think I'd get a new pipe and start over.
Sorry to see that you're a victim to such shoddy workmanship. The so-called welder who did this needs to be held accountable and cough up the cash for a new pipe, and then take some welding classes at an Ivy Tech. |

I just took a second look at that piece of work. Maybe the inside of the pipe is unharmed. The weld globs may not have even penetrated neither the primary nor secondary metals.
Either way, thats just sad.
I can't believe he took your money. |

I can't believe you paid the guy and left.
"I am a quality control weld supervisor, and if I went to inspect that weld the person who made it would be looking for another job."
That guy could not be employed at any manufacturing plant I've worked at. He obviously doesn't have a clue what he's doing. I would love to see the old manufacturing supervisor I used to work with tear his ass a new one - he deserves it. |

"You can weld stainless without having to use TIG, but as was mentioned above, he should have used TIG rod."
Yes, that's certainly true. An assembly I designed using SS sheet was welded on production lines using MIG, but you need the correct wire (and a competent shooter).
Weren't some XB pipes coated? Is that a coated pipe or is it bare SS? It looks almost like the surface was dirty and the welds were contaminated... or the wrong rod or wire was used. |

Here's how it ended up after they polished that turd.
It was a local muffler shop. I originally went to a machine shop, but they didn't have any bungs and pointed me across the street to a muffler/repair shop. |

That's still kinda grim.
I don't know if there is enough metal thickness in those tubes to have that much ground off.
It's all really sad. |

............ "they polished that turd."
A turds a turd polished, plated or painted its still a turd.
Looks to me like it was mig welded which is standard muffler shop work.
A proper TIG weld on a exhaust header whether auto or motorcycle should look like a row of dimes about 1/8 inch wide.
What did they grind/polish it with ?..... I could do a better job of grinding with a concrete saw....when I'm drunk.
You should have went across the street to the muffler shop and purchased the bung and had the machine shop pop the hole and weld it. |

well if it doesn't leak and you don't want to purse them to buy you a new pipe, you can always wrap the pipe to hide that mess. |

Or ceramic coat. |

I would be willing to bet that thy used steel filler material to weld that bung in and they certainly did not purge the inside of that pipe when they mig welded it...
It will probably rust in the next month or so unless you coat it with high heat paint or ceramic, but even if you do coat it its still going to look bad due to all the porosity (the little pits and holes) that is in that weld... If i welded something and left it like that even after they polished it I would be given a week off w/o pay... |

I wonder if they didnt know it was going to be visible at all times? Most of the street muffler repair shops dont try to do the best work. They charge you little money, and slap it together for you. They are most likely not used to working on pipes that are visible at all times, so probably didnt care how the finished product looked, just as long as it "worked".
The polished job doesnt look too bad. I would save up some money though to get it ceramic coated. Try sanding it yourself by hand first too to get it even smoother and more proffesional looking.
How much did you pay for that job btw? |

It was 30 bux. I'm not too worried about it as I bought the pipe specifically for mounting the bung on. I have my original pipe that I will put back on when I'm done. I figure when I'm done I'll loan it out to whoever wants it to tune with so it won't become a paper weight. |

Yea in that case, I wouldnt worry about it too much either man. I would try and get something coated over it so it wont rust, or did they do that again after polishing it up? |

Out of curiosity, how difficult is it to weld a steel bung to the stainless steel header? Could that have been the problem here? |

its easy, i would have tigged it wit a stainless rod, they mesh pretty well |

I'm afraid if I had to look at that as I was walking to my bike to climb on I would  before I put my helmet on. |

Yes, it's a basic job. The dissimilar metal is an issue but not a big one. You look it up or read the box to see if the rod is the right one. Not so much an issue if you TIG.
Are the flanges on the pipe stainless?
The weld itself is basic, in weld school you'll do dozens before you get past that level. In practice, most welders will run into it quite often. There's a certain pride, not apparent here, in getting a smooth, even weld in one loop. |

$30 is nothing really; I guess you've just learned not to have muffler shops do this sort of thing. Probably should have bought the bung there, then taken it to the machine shop.
By the way, stainless steel does not rust. That's the whole point of it. |

O.K. here I come with my two cent.
First, stainless of any kind WILL rust if exposed to carbon. What I mean by this is that the 'polishing' the manager did, was probably done with a grinding wheel that had been used on all the other carbon pipe they work with. This will in time (usually short) rust the surface of the pipe. Ceramic coating or any other coating will just cover this condition because the carbon has been ground into the stainless. Stainless steel just has less carbon, therefor less rust, get it stain-less. The carbon has been replaced by another element, usually nickel thus the toxic nature of welding stainless.
Second, if you are looking to get flow data from the pipe the worthless weld will greatly effect it. However if you are just looking at the O2 sensor data it may be O.K.
I may have a way to get that fixed for you, in Austin, if you want I just have to do some asking. |
