So, I'm bone stock and I am getting my synapse bov in tues. I here there is no way around cuting the stock recirc hose to fit the new bov. Is this right?
And If I wanna go back to stock I need to get a new hose?
Also im getting my cobb sri soon, will I have to do anymore cutting when that comes in?
 
You will need to cut more than the recirc hose. You also need to tee into the high boost line from the WG.

The recirc hose is no big deal, you can buy it at any auto parts store if you need to go back to stock.
 
What??? You don't need to cut the WG high boost hose!! Pull the hose off the WG plug a T fitting in it then run a little amount of hose to the WG and run hose to the BPV. That way if you need to go back to stock all you do is pull out the T fitting and slap the original hose back on the WG. I have the Cobb SRI and I did have to cut the recirc hose. I'm probably gonna get a spare here soon just in case I ever need to swap out. Let me know if you have any questions.
