Custom made backbox

[Semple]

any1 have any idea where u can get a custom made backbox from.

u can get 1 that has a flap inside the backbox and when the car hits the set rpm the flap opens, giving a sporty noise. and when its at idling the flap closes and the normal sound is there.

ive had a quick browse about and cant see 1, any1 heard of them or have one?

i've seen the ones with removeable baffles, but not the ones with flaps that open at certains rpm's.

why not just get an exhaust that gives a good gain, and forget the noise it makes?:homme:
