Hello, I have an 87 s4 rx7 (non turbo) and I just ordered the non turbo racingbeat catback. Now i need help with a setup from headers to the catback. Im pretty sure that the cats that i have now are clogged. Anyone have any idea what i could do from header to catback? I would prefer if it were something easy and could be simply bolted in. I also must pass emissions so a straight pipe unfortunately isnt an option.

thanks.

just in case here is the catback that i have ordered.

im not sure of bolt on, especially with the header, but have a shop replace your cats with a single high flow converter, I did that to my car when it was a NA car and it used to pass no problem.
