Hmmmm.
Are there any other options?
Go with the enclosed race valve. I had mine recirculated back into my Anderson Power Pipe. It is basically silent. You hear a whoosh of air when coming off WOT, but nothing the attracts attention. My fuel pump (Weldon 2025) is what is loud right now and I am replacing it with a couple of inline pumps for street use. For the track, you can't complain about a pump that supplies 1400hp worth of fuel.
