If you dont have a cat that works your up for a big fine or a defect notice and that isnt good. My brother and I just done an exhaust on his sprinter and its a 2 1/4 and straight through with one muffler and used a commodore cat as its the same diameter as 2 1/4 pipe.
Cats help to burn unburnt exhaust particles and if you dont use one your poluting more and can be in trouble with the coppas
