Will a complete dual cat back system from a 99 fit on my 94 ? A friend has one he's taking off and they sure look alike under there--Help.---o2 designs-Dad-Bob

According to this, no it will not fit. Not that you can't MAKE it fit, but it likely isn't compatible. NB cars used a mid-pipe with an integrated catalytic converter and the bends in the piping are different. I don't know whether the hanger locations are identical, similar, or totally different locations in NA and NB. Confounding the situation is the fact that the exhaust system you describe is aftermarket and unspecified. It could be possible that this particular aftermarket exhaust can fit both cars with a little bit of cutting and welding. But I think the probability of bolting up the factory flanges and exhaust hanger locations is slim to none.
