get a hks! there nice there better heres a quote from there site

"The HKS Super Sequential Valve is a dual stage pull type relief valve, which prevents compressor surge by releasing (either back into the intake stream or into the atmosphere) the compressed air flow that is normally forced backwards into the turbo as the throttle is closed.

Engine performance is increased from quicker turbo spool up as the compressor speed is not reduced by backwards air flow. The life expectancy of the turbo is also increased, as its bearings will not suffer from the impact that is common with compressor surge. For maximum performance the SSQV incorporates a small primary valve for quick activation that opens under light boost and load conditions and a larger secondary valve that opens sequentially to relieve pressure under higher boost and load conditions. The SSQV is constructed from billet aluminium for durability and has a high quality polished finish.

The SSQV’s are available as vehicle specific kits or as a universal unit for custom applications. Vehicle specific kits come complete with all the necessary mounting flanges, brackets and hardware for easy installation. For the universal applications steel, and aluminium weld on flanges are available.


Gold coloured triple fin inserts that produce the same unique aggressive blow-off sound, as the standard silver inserts are available as an optional replacement, as are metallic purple inserts that produce a lower frequency sound over the standard item. A re-circulating fitting, which re-routes the discharged compressed air back into the intake stream, is also available"

No.

What are your priorities here, having your car make silly noises, or having it run properly? If your priorities are the latter, stick with the standard one. If you don't care about that and just want to scare grannies, go for your life.

I'll second the HKS SSQV

I got one on the recent GB, what can I say.....some people love them and others....mmmmmmmm....well, ehough said. Mines on my MY00 and it sounds wicked (with the standard insert). If your close to ACE-CAFE (london) pop along and make your mind up for ya self mate [1st Tuesday of every month].

You'll also get a few POPS from ya exhaust ( Always brings a smile to my face )

You think this is a good thing? Have you bothered to ask yourself why it's doing that?

Yes Greasemonkey knows what he is talking about

That's WHY so many people have them fitted to thier cars

greasemonkey

Yes Chungster, I've had several offering to pay me to keep my gob shut!

Or even why so many people have been taking them off their cars and putting the standard ones back on???

I had turbosmart veeport on my current WRX PPP and took it off last week coz trading in for MY53 STi PPP tomorrow I was surprised at how much better the WRX was on re-fitting the standard plumb-back. If you have to get it out your system then fit one but bear in mind my experience. They add nothing!
