Thats interesting. They look the same to me LOL.
What I dont get is...The worst part of the crssover IMHO is the flex joint creating turbulence in the pipe which hurts flow. If you still have a flex joint, then what increase is there? Cant be size because if its much larger you are actually losing exhaust energy and reducing the speed of the exhaust gases. Wouldn't this actually be hurting performance due to unequalized pressure from the different banks of the engine? and isn't that what killed the injen pipe in the first place?
