I've never been able to diecide which bov I liked more so I have three (hks ssq,rfl, greddy type s) which I switch back and forth from. :P

 

haha got a wardrobe of bov's...thats pimp

 

I rock the RFL. Not as loud as everyone says it is. I thought it would be, but no, it's not to bad, atleast in the car. Different tones at different psi. 1-2 psi is a flutter, 5psi is a flutter/whoosh, 7-8 psi is a nice whoosh, 10psi starts to get kinda loud. LOL.

I'm using a Tial bov. Sounds like a whip cracking. Here's a pic.

 

^^^ that is next on my list :P

 

Bov from a Turbo SAB.
Sound depends on what you attach to the outlet.
From a Whistel to a whine to a farting sound.
