My QTP headers have an issue with the HVMC the primaries are not sealed by the welds looks like it never bonded Can I put some jb weld and seal them the rest of the way up? Or will it just bake and blow out. Seems like I have alot of questions after this install.

I have always had good luck with JB Weld but I've never used it for exhaust. Check to see if there is a temperture rating.

From my experiance with it, it may hold for a week or so, but with the drastic change, from very hot, to cold it will crack. Especially with the vibration. I have used the stuff a little bit, but never had any luck with it on anything as hot as header/exhuast. Id see if an exhuast shop could maybe weld it up while they are on the car.

Good luck.

You might want to try some stuff called quick steel. it comes in a tube and you can buy it at autozone right next to the jbweld. Ive had better luck with that stuf and its alot easier to use.

most auto parts stores have some jb weld type stuff that will handle 1200 to 1500 degrees.

Sorry for the newb question but can they get a weld in there with it all together? It looks like some shitty work by the crew at QTP the welds are sitting about 2-3 MM off the primary. I would like just to put some compound like JB weld and put it in a turkey injector and just layer it up untill it seals.
