anyone running the 3 inch downpip kit from r and d ? I can't seem to locate a used one from a ats kit for my factory turbo and would really like to upgrade to one since I had my turbo rebuild and intake wheel/compressor housing upgraded by @typ4. It just seems wrong not to do this simple mod at this point having upgraded fuel/intake/turbo and exhaust beyond the down pipe. I do have a banks 2 3/4 downpipe but the factory housing just looks undersized and I want to have turbo whistle at idle if possible it almost does now but not very audible
