They designed a new NIsmo exhaust just for the new HR engine.
Hey BMIKE thanks, but I was just told by Stillen (where I got my new exhaust from) that there is no difference in the 07 factory exhaust than on the 06 or 05 models. They say same diameter and they have an 07 that got additional HP on their dyno with the new system I got. They also said same suspension etc. just a complete new design motor which I already knew. Where did you get your info about the different size? Thanks.
