scott i have had a hks on my old p1 and the inserts are more cosmetic..they will ever so slightly alter the sound but look at the design of the hks and how the air escapes and then look at the bailey and that is what determines what noise it makes..hks with a standard airbox will chirp on lift off but will sound like a whoosh with cone filters as the air is coming back thru the filters as well.i got rid of the hks on my old p1 as it was too quiet and put a forge valve on and the sound was totally different..the inserts are like putting a different mouthpiece on a instrument but is is how the air is released that determines the sound.if people are happy with a hks fine but at nearly three times the price of a bailey i dont see the point as people only put vta dump valves on for the whoosh noise as a recirc does exactly the same job but without the noise..do u happen to have cone filters on urs or a enclosed airbox

I\'ve had the DV on both the twin hks cones filters and im currently running it on a single turbo. I bought the purple insert to see if it made much difference to the sound. So from my personal experience the purple insert lowered the whoosh, so much so i couldnt hear it inside the car so i reverted back to the standard one. From what i can remember the hks one has sounded the same on the twin filter (apart from the COW sound i used to get LOL) and on the single.

Im sure your baileys BOV does just as good a job as the HKS one but it wouldnt be very exciting if everyone was running the same engine set up, its good to have abit of variety.  :yes

i agree when running open air filters a lot of people think the dump valve is making a lot of noise.for a while i had a recirc on the p1 and cone airfilter and on lift off i still got the whoosh sound.i went for the bailey because it is very simple single piston on boost closed of boost big hole to let the air out and best of all about 80.00 quid..my fave though is the ones done by spec-r
