Who is running a gutted cat with a pipe welded inside? I'm in NJ would like to run a test pipe but don't want to not have a cat on the car ( with my luck a cop will impound it). Will the car pass NJ emissions with maybe an emissions chip and no cat?
Ed--Do you think my car would pass with a gutted cat and a Bob Bailey emissions chip? My EGR is functional. I really hate taking off the gutted cat once a year to put on a 'real' one for emissions. Thanks for your opinion.
