Default Does This Look Normal To You?

See that red spot right there...



So I bought a set of Borla UEL's off of Boxer4Racing (good turnaround, would recommend). First off, being a welder myself, let me say that I'm not too impressed with Borla's craftsmanship. Porosity, craters, rollover....






I'm sure those guys have a large number of exhausts to weld in any given shift, but at least clean the spatter up.

That's not what this thread is about though. My question is about where the tubing is welded to the outside face of the flange. Or rather, the lack of weld. It's only held together with small tacks on that side.



Now, I don't have any experience in fabricating exhausts myself; but in all of the other headers I've seen, there's a full bead run around that joint to seal it. Is this standard practice, or there a reason they only left it tacked? The only reason I can see for doing this would be to prevent cracking during thermal expansion. I know the early Borlas were prone to this. Would running a bead around the tubing increase the chances of cracking? Am I better off just leaving well enough alone?

there should be a full bead around the ID inside the flange. My TWE's are similar, as in they are just tacked around the OD under the flange, but they dont look like a 2nd grader on meth welded them. I think they just tack them to hold everything together then they can take them out of the jig and run a bead around the inside much easier. There is a thread that addresses exactly this, i read it a few weeks ago, and everyone else who has any headers said they had similar construction. a call to borla would clear this up in a couple minutes, too. good luck.

yeah I was pretty disgusted by the borla's I handled. You'd expect some quality out of a name brand, especially at the price.

And it's not just the n/a headers. WRX parts are just as bad. Those collectors are junky too.

Yeah, those collectors are pure trash.

People with Turbo engines should be very careful about any slag or bits of metal in their headers. When in doubt, grind it out. Also not a bad plan to run a sock on a string through the hidden parts of the manifold to try to detect any hidden crap. If the sock hangs up you should investigate. When a weld "drops through" a big drip of slag can form and then chip off destroying your turbo. **** happens. If you saved a lot of money, put in the due diligence inspecting the product before you install it. pressure or solvent testing the welds is not an excessive measure on crudely produced products.
