hey guys, as you saw from my earlier post, im getting an amuse stti exhaust soon, now im thinking of which y pipe to get, because the amuse is just a mid pipe.

these are what i have in mind

1)tanabe y pipe
2)amuse R1 pipe titanium ( a bit expensive but i was thinking if im getting the amuse exhaust, i might as well get the whole thing)
3)motordyn art xyz pipe, also a y-pipe, and it comes with hfc's.

if anyone has any other recommendations please chime in, and one more thing i was wondering, does it matter what y pipe you go with, does it affect the car sound wise?
