1g, 2g exhaust flanges

[WhipmastaFlex]

are the cat flanges the same on a 1g and a 2g? i have a pipe that i want to fit for a test pipe, and can get a cat for relativly cheap at the local junkyard, so can i weld the flanges on and bolt it up to my 2g exhaust?

The cat flanges are the same size but they are at a diffrent angle. the front of the cat will bolt up but the rear will be like 45 deg out

you prolly can't buy a cat at a junk yard as it is illegal for them to sell them....... maybe it's only ny that like thta idk......good luck
