Your mounting flange/piping looks like this.

is that the stock IC piping? if so it looks like i don't need a special flange. if its an after market flange/pipe, could you let me know where you found it? thanks.

All stock IC piping is aluminium. The pic above is not the stock pipe; it's the replacement pipe you can buy to mount the BOV.

i wanna know how that sounds when you got it on. what type of noise it makes.

i already know it makes a high pitch chirp like the HKS SSQV. i've got a friend with one of these on his Eclipse GSX. i love the sound and it performs great.

double posted.
