Well now I would hesitate on doing that if I were you until a few confirmations can be made. I spoke to a performance guy at Caffeine & Octane today that said that keeping them open slows the turbo spool up. Ugh! My guy is a guru too so I am not sure who to believe. I will find out more and post info.
Interested in the outcome. Many aftermarket exhausts have no valves, so that's key info.
