Im not familiar with that brand header but the welds look to be TIG and of reasonable quality, at least the closest one you can see clearly. The tubing looks to be the same on either side of the welds. Im wondering if they were cut and welded to match up with the muffler system? Possibly made a mistake with the middle tube, or had a blow out when welding it up originally and they chose to weld in a section to repair?

Regardless, I would check the inside of the tubes for the weld quality with a boroscope to see if the weld is clean and fairly smooth.

If it looks good inside, IMO there is nothing wrong with their functionality. A little work with a Roloc disk and you should be able to make those weld nearly vanish.

The guy should have disclosed that IF he knew it was repaired, but this seems pretty minor if the inside of the tubes are clean.
