Hawk sti induction kit?

Going to get an induction kit for the hawk sti & get it mapped in for the car, but which one?
Loving the dump valve noise (ta Mario & Discodaz) and gonna get a few pops n bangs mapped in as well & possibly auto intercooler spray. I'm not after anymore power as Anthmac has already put the heebeegeebees on the engine as it is! It's purely cosmetic/sounds only really. Would like some turbo flutter noise, but would that negate the operation of the dump valve?

So anyways, which induction kit & where from?

Could be worth a call into revolution mate and see what they suggest. I've got a piper-cross on mine and it gives off a nice chatter but if I give my car more beans the dump valve kicks in. I've only got the piper cross cone fitted on mine and it works a treat

Must say Nick, their prices are very good compared with other websites out there, so probably will give them a visit, AndyK is mentioning the k&n kit with the backing plate thingy ma jiggy.

typhoon   

Got rcm on mine give mint Chatter no dumpvalve

k&N Typhoon kit with the engine bay separator to prevent heat soak.

Or the perrin cold air kit which is very good similar to mine on the saloon and it gives a great induction noise.

Or the RCM kit which is a fortune.

you can get them cheaper if you look around

Many thanks for all the advice, after also speaking with Bob R, decided to go for the RCM one, same price as the K&N one from revolution.
