Efini Y-pipe
I have a polished efini pipe on my 7 and i have noticed a good deal of difference in spoolup time so for this alone i would do the upgrade. Not to mention that you dont have that lame *** coupler.

Only problem I see with the Efini Y-Pipe is...
you're limited in aftermarket ICs. I'm interested in the M2 large IC, and from what I've read so far, only the Greddy and PFS ICs will work without modification to the Efini pipe? I like everything else about the Efni Y-pipe. For me, it sounds like I'll need to bleed off more boost to maintain 10.5 psi to remain compatible with my stock ECU?
