i'm thinking about getting this manifold as many people on HMT have had great results on it...it comes with a flange with a 2" 90 degree bend for the downpipe for an extra $40...i was wondering where i could find a 2"-2.5" transition to get it welded it on? I tried searching but most of the threads that came back were for 2.5-3.0"....thanks
