So it's been a couple weeks but when they re-diagnosed it they found a crack in the header at the flange of my KillerB holy header. Now they do have a lifetime warranty but unfortunately thats only for original buyers and I bought the car with the header on it, they also said that there is a leak at the V-band between the header and uppipe so I guess I'll try a new clamp but I don't think that'll fix the leak. Going to try a couple of things with that v-band mating and report back but ill be welding that flange crack and see how it goes
