Hello! After unsatisfactory afforestation of Sufu 113 hits I would like to ask if there are more recent experiences with test drives with a V60 T4. In this context I would like to mention that it annoys me that my intended and preferred D3 has only a single-flood exhaust system, which makes the rear view rather unsightly compared to a D5/T4 with two-flood system and chrome blinds. I want to leave the design package for both versions outside. What is the technical reason for a one-flood or two-flood exhaust system ???? Is a cost difference after a few years when exchanging e.g. because of corrosion? Who can share his knowledge and the experiences with us with the T4 ?? Greetings to everyone !
