Exhaust Leak on new HX40 Setup HELP!

[PredatorSniper]

This is driving me nuts. I just welded up a new 3" downpipe V-Band to my HX40 .70ar BEP housing. I bought a new ERL cast T3 manifold put everything together and I have a slight sound of an exhaust leak. Now I didnt' think this was a bid deal at the time, when I bolted the manifold up to the head one stud must have been stripped cause it just kept on spinning and spinning. Is this the source of the leak that one stud couldn't be tightened down, I mean the face of that ERL manifold is all one piece? I have a MLS gasket also. So the main question with all this new welding and mock up of this new downpipe and manifold where is my exhaust leak? How can I find it?

Smoke a cigar or cigarette and blow the soke around the exhaust where things are attached and watch. The smoke will blow away from the leaking area and that should help narrow it down. And you should fix that stud anyways as well.

Or get seafoam and run that through your bov line and look to see where it s coming out.
Use enough that it is smoking out of the tail pipe.

If you welded the vband yourself and didn't have it bolted on the turbo you could have warped the flange.

this most likely, also u can put a smoke machine used for checking EVAP leaks in the tailpipe then stuff a bunch of rags in after it and turn it on and it will fill the exhaust system with smoke and show the leaks. thats how i used to check mine

Simple approach maybe... Small piece of paper on pliers while the car is running and hold it around the flanges and see where it starts to flap.

I like the paper clip and pliers thats pretty gangster

I'm battling a bad exhaust leak where the turbo flange meets my header
