FI Non res vs resonated CBE

Honestly. It all depends on how sensitive your ears are along with how much "noise" you're looking for in terms of Exhaust sounds. When I bought the NR CF i had only heard a 12" Res + NR HFC in person, and I couldnt stand the added "hiss". And it was a DEEP sound. I would say 12" is the perfect midpoint for Loud (when on throttle) and quiet when cruising. Just know in colder temps (50Fs and lower + cold starts) will be even louder.

I'll post a vid from inside the car later tonight (again it'll be NR CF).

CF = Higher pitch 3K Rpms+
SS = Deep = Entire Rev Band
