Same for me... for now, anyways. I ordered the FI CBE with 18" resonators, which I'm thinking will be loud enough for me. If not, maybe I'll add HFCs... but only if I'm sure it won't be obnoxious.

HFC will not make it obnoxiously loud unless you are WOT all the time. If you drive normal speed limit and keep your revs under 3k it's not that loud.

The HFC definitly make the car sound modified and that is what I didnt really want. Its not a bad sound by any means, it just isnt refined like the exhaust note of like a Porche or something. It sounds like a tuner.

Now I would tell anyone who is considering test pipes it will border on the obnoxious loud side and will sound raspy. Even with the HFC's there is a little rasp at WOT but test pipes would amplify this.
