@@benboy80 hey Ben, yes it does so whenever you have a “Cat - Back” as far as I am aware it means that the Catalytic converter is still factory and still CO2 compliant. And that you no longer have a back box beyond the rear axle. I hope that makes sense?😊🙏
@@Sprocket_abarth yeah I get you, I think some systems still keep a resonator or silencer box, guessing from looking that the toyosport does away with it, sounds great and not too loud 👌
