Does anyone know if a universal 3way catalytic converter will work on an 88 GXL with 6port 13b engine? I know that tube on the catalytic converter has something to do with the 6port actuation system. I just wanna know that the 6ports will work fine with a universal 3way cat. I'm just trying to sell me car but I don't want to run like **** either.

Here's a Nice High Flow Direct Fit Converter for 86-91 Rx7's from Summit Racing which sells for only $99

they also have a universal which sells for about $50 if you want to install it yourself but requires some welding and fabrication to fit.
