So after many posts and ranting and blah blah, I finally got my Synapse BOV installed...sorta.

FYI: Synapse syncronic bov DOES NOT fit well on stock MS3 without some tinkering.
1. Stock IC cover hits it as well as stresses valve C
2. Angled the way it needs to be for COBB Sri, it hits the stock airbox.
3. You will have to plumb 3 new hoses with 1/4" or smaller T's or Y's. The boost only line by the wastegate takes a little time and skinny hands to get at.
4. Stock recirc hose will have to be cut to fit ( I also rotated it 180 deg)

Other than that IT WORKS!!!
Noticable difference in boost response throughout the gears.
Its not very loud with stock airbox but can be heard somtimes with windows up and radio off.

I guess thats it for now, I hope this helps people considering it. Great product though, I just want people to be clear that it's not simply bolt-on and go. My COBB is OTW so I'll be much happier then.(idhitit)

Ill try to post pics soon of my install
Any questions?
 
you will enjoy the Cobb. The BOV will be so loud! I agree with the boost response although I wonder if the Forge would have done the same for less $$. Ill feel better when i put my FMIC in and the synapse has more clearance though.
 
Yeah the stock BPV stocks wicked with the Cobb so with an after market one I'm sure it will sound pretty insane
 
Do you have a DH? if so, do you think you can post a couple before and after logs....if you can. If you can't no biggie.
