Fast Intentions exhaust is here!

What I find strange is that sometimes it is really loud, and other times it is not that bad at all... just wonder if it has to do with the environment. For example, the exhaust isn't as loud on the way to lunch. On the way back from lunch, it can get pretty loud (interior-wise). Overall, if you rev past 3k (even full throttle), the sound is sick and is nowhere near as loud when hovering around 2-3k.

I'd be interested in hearing how loud the 2-3k rpm drone really is. IMHO, this is the WORST range to have drone as you're sitting in this range while on the highway. If it's minor though, perhaps it's a non-issue. I'd ideally have no drone or drone in some range I rarely use like >6k rpm.

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.
