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).

i'm just curious as to how much power loss there is using the stock cats.

Just curious... it looks like the FI exhaust gets the most gains.

I have seen some of my customers have recommended the stock cats and the CBE with 18" resonators. This combination should be more than quiet enough for you.

Weather you are ready to make a purchase now or down the road, please do not hesitate to call me now with any questions that you may have...

Thank you, Tony

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.
