I have 2 catalytic converters for e30s, they are from Colorado, so heat shields are in good condition, I took them off 1 manual and 1 automatic trans, but it has been so long that I donít remember which is which. I need some help identifying the application, so I can sell them. Both are twin pipes the full length. I am asking $100 + shipping for each. I would appreciate any help with this, let me know if you are interested in them. I can send pics of the attachment point brackets so you can check the fit. Thanks
