The Gents over at Rogue Engineering did the Diablo exhaust install on my e60 M5 today; it's siiiiiiiiiiick:grinyes:!!!!! I'll keep all informed of the gains (Yes, there are gains) from the new can setup over the next couple of days. Ripped some back roads up an hour back and had a smile from ear to ear!
