as stated its a 4th gen stillen charge pipe that came with the stillen kit. Included is the 90 rubber bend and the stock bypass valve

I currently have that piping with the bypass valve. I'm looking to install a new blow off valve. Curious as to if that is what you did or not? Can you not put on a bov without replacing the stillen piping?

 

i did not change the flange on the stock piping. That is what you will need to do if you want to put a bov on there. IIRC you don't need another flange if you got a blitz bov cause it fits on the stock flange. If not you will need to cut the old flange off and reweld the correct 1 for the bov you have

 

ok, thanks for your help!

 

You have PM.
