I was just about to do the Pedro mod but my exhaust man and I started to get nervous about how close the pipe would have to be to the bumper. I had just deiced to save my coins for an aftermarket exhaust when I saw this mod.
Has anyone ever tried to bypass the secondary cats with… oh… say a piece of rebar or some ridged conduit? I have heard people talk beating the hell out of cats to break them up and create more flow. I wonder how hard it would be to ream out the secondary cat.
