Exhaust leak
Ive had an exhaust leak since I switched out my exhaust out. Ive got the stock headers/cat to a 3" HKS midpipe and Blitz catback. The leak is in between the flanges of the stock cat & midpipe.
When it was first put on, the shop said i needed a gasket and sealed it with RTV. That blew out quick so i ordered a few 3" exhaust gaskets. I figured this would solve my problem, but nope still leaked. I even tried doubling up on the 3" gasket, but there was still a leak. My last attempt was a recommendation from a friend, ultra copper sealant. Just like all the rest, this did not seal the leak very well.
Recently got my inspection done and the guy said i needed to get the leak fixed. I also noticed a decrease in mileage since it first blew out, so i just wanna fix the damn leak. Theres a gap between the flanges, and thats where the leak is coming from im assuming.
Anybody have this problem before, or have a solution? This is only temporary for a few months until I swap out my stock motor for a 1j, which means i wont have the stock cats so hopefully this problem wont exist.
Heres a pic of the flanges, incase it helps at all.

damn, was hoping i wouldnt have to go back to a shop. Would it matter that its going to a bigger exhaust if everything lines up correctly besides the hole?
Whats the point in cutting off the current flanges to put 3 bolt flanges? The stock cats arent staying for long
