Hrm...I thought Rygen showed that going from a dual with reverse Y-pipe to an X-pipe only gained 1 or 2 HP...I didn't think he did any single vs. dual dynos...did you Rygen? You've made so many changes it's hard to keep track [img]style_emoticons/<#EMO_DIR#>/icon_mrgreen.gif[/img]

LOL. I had a dual Y pipe kit, then went to a dual X pipe, gain was 2HP. Did a before and after dyno.
