Installed the STillen g3 intakes and Berk HFC on the Nis this weekend. What a big difference over stock, love the sound and the car comes alive at 4k rpms. More so then before. Unfortunately I Do have the Rasp
But I mostly here it when powering thru first and then can't really hear it thru the other gears.
Hopefully it will go away in time or I might have to upgrade the CBE. But I like the sound, hopefully the rasp will go away.
