It gets pretty loud if you give it some throttle in 6th gear in the 2-3k range. It's enough to rattle a few things and drown out the music. If you ease the throttle and coast, you can barely hear it. So casual acceleration hovering below 3.5k RPM can get quite loud if you give it up to 50% throttle. The exhaust sound gets quiet once you rev past 3k. Even at redline it's nowhere near as loud compared to the 2-3k range.

Now this is with the HFC and x-pipes with 12" resonators... which isn't a quiet solution. Hence, I'm waiting for x-pipes with 18" resonators.

Yeah I have the 18" and the same thing applies as Digi states. Maybe not loud enough to shake panels but still loud enough to drown out the stereo or something. I really wanna try the FI HFC for hiss purposes though. I may go back to stock cats and put some G3 on instead to make up for power diff or I may just add the G3. :)

Yeah my bad, I made that post while on my lunch break and was in a hurry. I have 18" resonators and that was just the exhaust. I have HFC on now and they make a difference but minimal. I'm thinki thinking the G3 will make a bigger diff than the HFC.

B1nks, did you make a video that I missed?

No, not yet anyways but Digi is very true about when adding HFC. The hiss that the Berks give off really ticks me off. I LOVED the exhaust before the HFC with the hiss. The car was dynod on a Dyno Dynamics at approximately 80 degrees with medium humidity for south Texas. :tup::driving:

its not just the berks that hiss. its pretty much all HFCs/test pipes

It's muh birfday :(
