Im building a client's 95 canter 4x4 double cab overlander with the 4d35 engine. My question is were doing a turbo setup with 3" exhaust. Does anyone know of a factory vacuum exhaust brake with at least a 70mm port. Any help would be greatly appreciated. Ive seen other people speak of f417 exhaust brake but it seems to have a different style setup. Any help with this would be amazing
