Diverter valve options

The nipple on my stock diverter valve broke when I was trying to pull it off to do a smoke test(checking if their was a manifold gasket leak). Previous owner replaced the charge pipe with a vrsf unit and kept stock diverter valves. Since this charge pipe doesn't allow for a bov I need to get a new dv. Most of the aftermarket dv valves I've seen are $500+ so are their any other options that are more affordable? It's cheaper to get a whole new chargepipe bov combo then a forge dv

Get the correct flange for your desired bov and take it to a shop and have them weld it on, roughly 300$ depending on which bov you get

Best option. Can set them up to VTA if you want some sound as well, I think they may do 50/50 VTA as well. If I remember correctly he has used these over 20psi no issues.

I actually had these for a short period of time before swapping to a Tial BOV. They worked and I was boosting around 22 psi.
