hi everyone, i know this is a touchy subject with some of you guys, but now i have got my04 sti ppp i have to get a dump valve! After hearing a scooby passing with the phsssstttt between gear changing i need to get one.

don't want to be super loud, but loud enough to be heard would do.
i know some say that they are not good for your engine and can effect power output but surely big names like HKS and Blitz would not supply them if this was the case???

any recommendations

A decent high flowing panel filter and removal of the induction resonator will make the OE recirc DV audible, as well as the spool-up and induction noise. It also feeds the engine with more, cleaner, cooler air and all for about £40 for the filter and 20 minutes to remove the offending black plastic bits. If you want details then ask, otherwise open your wallet.

Hello mate, what do you mean by the "induction resonator" and which parts can i remove?

I have a STI panel filter at the mo.

Cheers.
