The RFL is made by TurboXS, here's a link to the product http://www.turboxs.com/more_info.php?ID=6. I currently have this in my car, I have a first gen DSM BOV that I need to crush, but I haven't decided which I am going to use.

 

the rfl isnt that loud! my hks SSQ is way louder.

 

how loud is a greddy type s?

 

you know, blow off valves actually serve a purpose other than making a loud sound.

 

the greddy is hella loud!!! i know i had mine mounted by the intercooler outside of the engine compartment and i scare the ---- outta people when i shifted....i like the way it sound and u can adjust how hard it hits...

 

Really :1

 

lol

 

ha ha ha thats funny thanks for the help guys...........

 

on 15psi mine is loud as hell

 

my dsm BOV @ 10 psi makes a really nice phhhksshhhhhhh i'm a lot happier with it than i thought i would be with a stock bov

you can always buy one of the RFL knockoffs but that sort of gets to the point where that much blowoff should really only come from a 2JZ or something lol
