 FI LTHs + CBE is actually quieter than HFCs.  In cabin, windows up/windows down, still plenty quiet enough to enjoy music, or conversation. When you get on it, you hear what you want. Changes the tone of the exhaust to a slightly higher pitched note due to the increase in airflow. But the brute 'Volume' is actually less.

Here are my Dyno Vids:
I used my GoProHD on the window looking inside so you can see the RPM's and use that for the audio, since I stood behind with my phone to do the rear video's, so that's why the audio goes to crap. Just the sheer power is a bit much for the mic. Once I get a little more work done, I'll take some more dyno vids from a different angle.

 I went with the FI SS CBE + 18" resonators (stock cats). I think it is just about the perfect sound level wherein you can still have conversations in the cabin but it still has enough extra dBs which improves the stock Z exhaust sound (without drastically altering it) nicely. There is no rasp whatsoever, the exhaust note is very smooth.I am on the fence about upgrading to a HFC because I want maximum performance, but am afraid of being too loud (drony). |

Go to the first page of the FI thread (the super long one). It has the dynos on there. In summary you get about an extra 20 hp by simply changing the exhaust. Adding hfc's will net about an extra 7.
