Mine went on my CLS GE and i fabricated a bracket from an exhaust clamp and a lot of trial and error , in hindsight i should have just taken it to a exhaust fabricator and had a new (proper) one welded onto the pipework and had the one on the other side replaced at the same time.
Got a pic somewhere and it would have made Heath Robinson proud , for the time i spent at work getting it right it would have been cheaper for the company to buy me a full Akrapovic system.
