Has anyone any experience with the 335i style exhaust from insidePerformance (Germany)? They have one tailpipe left - one right - like the 3 series 335i / 335d
A friend has the quad m-style exhaust from them and is satisfied.. but this 335i-style seems to be new
Anyone having it on an 135i N55? I am interested in some soundvideos and some more pictures..(if possible on a blue 135i - they only have this white 1series in their shop)
