So, on g35driver.com I was told that AWD version will come very soon! My friends on the russian Infiniti forum (club-fx.ru) are waiting for them too, as I made
some presentation of the ART pipes and people are interested in them (btw, we all got AWD sedans, no RWD option for the Eastern Europe).
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...
