Currently, on my VQ35HR I have: Berk's HFC -> Moroso Spiral Flow 2.5" resonators -> Borla H-pipe true dual cat-back. Borla itself is rather raspy and loud, but when I installed Berk's HFC the rasp and drone were unacceptable to me, so I put Moroso Spiral Flow resonators between HFC and cat-back and it really helped.

My question is: should I remove these Spiral Flow resonators when I install ART pipes to my Borla or leave them at place? I beleive ART pipes would be less raspy and loud than Berk's? And I'm not sure if these 2.5" Spiral Flow resonators affect the perfomance (hp/tq) - though they shouldn't...

Yes, we are working on it now. In fact, the change is already made. What needs to be done is confirmation of fitment on a number of the AWD vehicles. What fits on one test vehicle doesn't necessarily insure it will fit on all AWD vehicles due to car to car tolerance variation. But this will be quickly resolved once it goes out to several local AWD vehicles to confirm fitment. As for the Moroso resonators, keep them in, I can't see how it would hurt in any way.

We also used the change opportunity to make a couple other new improvements.

1) The hardening fiberglass has been eliminated so there is no longer a break in period.

2) The retainer screen has been eliminated. Its what originally trapped the beads and created the bead rattle problem.

3) Many people have been requesting the Chrome ceramic coating. ...And now we can. It couldn't be done previously due to beads getting trapped behind the screen but the screen has been eliminated. So now there is no longer a particle trap of any kind. The chamber is easily and completely cleared out before installation by simply turning it upside down before putting them on.

4) Vibration dampening tabs that connect to the stock catalytic converter brace are now included. These connecting tabs are not connected to, or for structural support, of the main pipe. The tabs (or bracket) is connected to the side branch only. These connecting tabs greatly damp the engine vibrations transmitted into the resonator and make for a quieter ride while cruising.

5) High temperature silicone RTV is now included in every kit. It is to be applied to the inlet gasket upon installation and will insure a good permanent seal.
