Y-pipe decisions

chrischhorn

So..... I'm kind of in a toss up on deciding on a new Y-pipe. I have the litespeed racing full catback exhaust but I feel the the y-pipe is sub par so I wanna swap it for a better designed one.

So now the toss up is between the

Motordyne XYZ:


AAM comp Y-pipe:


Tanabe Y-pipe:



Its clear to see that the litespeed one is an OEM style with bigger diameter piping but I feel the flow isn't as efficient as it should be due to the bends. I have a feeling where this thread will go with "Motordyne all the way" but I figured I'd ask anyways. Any major differences between the 3 choices I have as far as flow and design? I know XYZ you can change the straight pipe to resonated or hfc but I won't ever need that lol. HP gains is my only concern. Any links to prove responses would be great but I feel like this may just be a toss up.
