Message	I've been searching around and can't find any solid reason our cars in TT form require a x or h pipe to optimally perform. It seems like it may be a point for back pressure to me especially since they converge but can't scavage. I'm very curious the dyno numbers x pipe vs straight pipe. Any numbers out there?
