1.I have been running without a cat now for a while /forums/images/graemlins/ignore.gif, and now my tags are up. I need to get one in there, But it would be a pain to put one in in front of my muffler. However it would be easy to put one in there after the muffler (about 3'-3 1/2' away from the colecter) Would this stil work to pass emissions test? Or will it not get hot enough to make it work properly. 2. Also anyone know any tricks to help it pass the sniffer/dyno test? (1990 3/4 ton sub with 350TBI 200,000 origanal miles.) /forums/images/graemlins/ears.gif 3. Anyone got a good cat layin around?
