ha! what do you think gutting means?...remove your cat.and then hammer the shit out of it with a metal rod,to destroy and remove the honeycomb,then simply reinstall it.........good luck passing emissions if you have to........or buy a aftermarket down pipe,i understand they eliminate the pre-cats all together
the Precat's eliminators from DN are very expensive, the back one must be crazy to make, you can have a local shop make you a front Mandel bent Pre-Cat eleminator for under 75$ and you are better off gutting your Rear Pre cat, unless of course they run emission test in your area, then you should make sure your have a spare one just in case... (I bought a used one of the list for not too much)
