I think R3V answered it. I just did not expect this car to backfire, (or what ever it is). I hear it a lot on loud V8s.

The noise you're talking about..."pop pop", is more of a backfire. This is most common in the nonresonated setup, which IMO is just "pissed off" sounding! It doesn't happen every time, but on an occassion when you hold your rev in the higher RPMs and all of a sudden let off, you'll get a "POP!" Puts a smile on my face very time!

Also while on the subject, I'm assuming the FI resonated HFC's would cut down on any drone noise compared to non-resonated HFC's. I already have the 18" resonated CBE, but wouldn't mind it being louder at WOT. Cruising volume is ok to me and I would like to keep it where it is, or maybe just a TAD louder.
EDIT: Off topic note. Love the sound of the exhaust when I'm driving in the parking garage at work. Also love the fact that some car alarms will chirp when I drive by  |
There isn't necessarilly an "advantage" to not having the mounting brackets, they just aren't required to have is all.
The RHFCs will cut down slightly, but not a ton. I personally have ran RHFCs on the G37 setup with 18" in the X, and currently run RHFCs with NONres X. Drone is more prone from the Xpipe then trying to stop is immediately out of the cat, but since you have 18" resonators in the X already, you would most likely notice an immediate difference w/ the RHFCs vs HFCs.
