Help/advice with exhaust manifold probs!
So my stock exhaust manifold failed like many at the welds around the pre-cat. I didn’t want to dump a bunch of money into the car because I probably won’t keep it much longer and I ordered an EBay/amazon header with the test pipe/resonator.
I installed said Ebay/Amazon and it sounds like crap! It’s raspy and noisy and sounds like there is a leak and I hate it. There is also a horrible drone and vibration and lower RPMs. I double checked all the connection points at the manifold and the gaskets and all seems fine.
My next thought was that it may just be the lack of catalytic conv. that is creating the problem, so maybe pull the stock cat off of the OE manifold and have it welded up to replace test pipe. I found that no shops will touch it because it’s illegal to mess with the cat apparently.
Question now is...should I buy a used stock exhaust manifold or have a universal cat installed? Help!

Try seeing if they will weld the stock CAT on the new exhaust if "you" remove it from the old exhaust.
Either that or pull the new header back out and try to find a welding shop or home welder to do the work, instead of an exhaust shop that has to worry about the legality of it all.
