n55 doesn't have cats in the midpipe just a resonator. And yes the Single turbo could have a little do with sound N55 sound ftw ?

n55's diverter valve sounds like that. you can even hear some bov-like sound with stock airbox. intake just amplifies that sound by 10x.

Does that air sound have anything to do with Stage 2 controlling boost differently or is it mostly the intake? I've got catless downpipes and a stage 1 and it doesn't sound anything like that.

The bov is coming from the addition of the intake. Most of the spool is coming from the dp.

Do not confuse my setup with your n54 twin turbo you will not get the same results.

Nope it doesn't Hurt to have over 10 psi but it sounds the same when I'm on the Stock map ..

Get an intake since changing the oem diverter valves will be a huge pita since they are welded to the turbo.

It sounds great. I figured the intake was making the the diverter valve noticable louder in sound. The catless dp will make it sound completely different even running it through a stock catback exhaust.
