60rk Posted October 30, 2007 Posted October 30, 2007 Hi All have a sigma 150 almost run in, and already thinking about the above mod. Has anybody done it? Any links would be appreciated. John

paul jacobs Posted October 30, 2007 Posted October 30, 2007 Not with a Sigma, but I have taken the cat off my 260 Duratec, but sad to say I haven't noticed the extra 3-4 bhp it's supposed to release . It could be more noticable on an engine producing 150 bhp though Paul J. Loud pipes save lives, but quiet ones save your hearing.
