Hi not my car but a mate has got a mk2FRS he wants a dump valve ,so i said maybe a bailey/forge/collins one with new pipework so if you do this what do you do with the std one that i think is a recirculating one ,do you take it off and block up the hole.Another option i see is forge do a billet uprated one recirculating one would this give him a good sound ...Thanks

 

Stick an induction kit on it, it will give you chatter and get a bit of performance increase too

 

what sort of kit do use richie .

 

I've got the dreamscience kit on mine, it is an overpriced load of shit though. There's plenty of others about though

 

The Dreamscience one I had was loud. Nice chatter when coming off boost as well
