the bov have a low flutter. yes you can hear it under boost. no, it's not a rfl bov like the evo's and sti's. this system is really low key. with the stock bumper the car looks completely stealth and sounds lightly modified....until you drop the hammer. if you are looking for a in-your-face-i got-a-turbo type system, the aps st is not for you. turbonetics is more showy and has a louder bov and puts out comparable numbers. choose your weapon wisely.

 

Bullit -- you hit it on the head

Honestly, I think the sound has gone down since the install, because they took out most of the borla -- the kit comes with the piping through the mid way of the exhaust

even when you open the hood, you can't see the turb -- which is good because the cops in California are up on what to look for

 

if you want some more sound from the bov, you can do what i did, take off the recirculate hose that feeds back into the intake, and cap the intake port off, then take the hose off the bov, that makes it much more noticeable.

ive gotten used to mine and i want something louder, thinking about the HKS SSQV.

 

only problem with that idea is that i heard from someome you can have stalling issues with this kit if you don't recirculate. if that's not true maybe more people that like that sound will gravitate to the aps st.

 

is the aps st kit have the same wiring harness as the aps tt? basically do u have to hard wire it?
thanks

The wiring is the same as the TT just plug an play no splicing.

 

had it that way for 3 weeks, not a stall yet, recirculating doesnt affect how the car runs, its only for lowering the noise of the bov, thats all.

 

what are you guys talking about hardwiring?

 

Tig, my bad.... any splicing of the sort is what i meant.

captj, thanks for the info.
