i broke a flange on my header and replaced it bud my bud said hey lets take off both cats and take them out should have never done it so on the driver side instead of the nut turning the nut was stuck to he thread and now where the header and cat are there is a gap and it sounds like crap so i tried to tighten that back up and now all it is stripped so .............. i need help does anyone know if a shop can do anything about this?

If I'm reading this correctly, the nut at one of the collectors is stripped out? If so, why not just buy a new nut or go to a larger bolt?

I feel like I'm misinterpreting this, if so, sorry.

well i forgot to mention that the bolt is not all the way out its stuck and now i cant do anything so there is a gap at the header and the cats where the connect

try taking some vice grips or something and turning it that way...you said its partially out so im assuming its not torqued down. also sometimes what works is say the bold is metric, using the next size down but in american sizes will sometimes get it too, if that makes sense.

thanks ill try but does anyone know sense im pretty much running one open header if this will cause a loss in horsepower cuz i moved my car and i can usally move it without any gas and just lightly let out on the gas but this time it wanted to die is this becuase of no back pressure or do i need to check my spark plugs becuase i took them out so i wouldnt break them when i took the header off

i might be a little late on this reply whether you fixed it or not....not sure about the horsepower question...if you got the header off along with the cats, try the vice grips...works good alot of times...if you can and the nut is a "seperate piece" take a thin dremmel and cut the bolt right behind the nut and replace it. it not....i dont know what to tell ya
