And Stage3, yes you need 2 of them. The only problem I've heard with them is the springs getting weak after awhile and they start leaking. I haven't driven mine in awhile but when I did I had no problems and they didn't leak during boost leak tests, but I never filled it with more then 10psi for testing.
Thanks buddy, do the rfl's sound as good as they do on youtube?
