I have to pass emissions...but there is no visual inspection. Does anyone know of a specific brand of lt's that i can some how ghetto rig a bolt on cat when needed to pass smog? Greatly appreciated, Jason

 

In your exhuast piping just cut out a section thats big enough to fit a cat, and weld flanges onto it, then weld flanges onto your cats and then onto a straight pipe. should work fine, that was going to be my plan untill i found a guy who dosnt even see the car :P
