If you go with a weld in unit, get a weld in flex joint with a 2.5" minimum ID, and cut the factory flex joint off.

Also, for information's sake, it is illegal to install a used cat from another same, or different car. You probably won't find one in a JY partially because of this. They cannot sell you one. The value of the platinum is likely the real reason.

Well unless the cat is drastically different looking than what should be on there, and it passes a sniffer test, who is going to know?
I'd like to see an inspector prove the thing was from a different car, especially if it was from the same model and year.
There are probably not a lot of shops that will risk the fines doing it, so it is mainly a backyard thing, so it's kinda tough to regulate...

Replace it with a weld in flex joint.
The magnaflow was a direct fit, so yes it had the 1/2 o2 bung.

how does that flex joint go on to replace the origional one? I asked my mechanic if he could do that and he said no. Should i just pull one off a junker and put it on to replace it?
Pictures of how it would be welded on would be GREATLY appreciated

Try a muffler shop ... a good one has experience fabricating custom exhaust, and expert welders ... this isn't general mechanic work.Nathan9790 wrote:how does that flex joint go on to replace the origional one?
