Probably going on a limb here but... I've been looking for the old helix exhaust (rotary extreme) but came short because the exhaust has been discontinued and was wondering does anyone in the bay or know of anyone that have one that they might want to get rid of? I've heard 8 rx8s were test fitted with this particular exhaust in the bay area, and am very interested in hearing it in person and possibly purchasing it so any help is appreciated.
