When I had the same question I ended up getting fast intentions reasonated test pipes. They did not change the sound of my current exhaust by much.

test pipes give you more power, only a little more than HFC's. test pipes are supposed to be more raspy than hfc's but i have heard them both and sometimes hfc's are just as raspy if not worse than test pipes... it depends where you live if they are illegal or not, in cali i heard its 1500 dollar fine if you dont have cats.

I'm also looking for quality resonated test pipes for my 07. I found Fast Intentions but those people are pricing their test pipes close to $400.

Some companies are going overboard with their profit margins.

Federal violation of Clean Air Acts IS illegal in every state however many states don't enforce.
However if you turn yourself into EPA they might fine you $10,000 or confiscate vehicle until you pay for restoration to oem.

It is also illegal to replace oem cats when they are in emission warranty. Shops must store and produce old defective cats or face fines.

The point is why would anyone pay to replace GOOD cats while still in warranty. Obviously trying to break law.

Where many get in trouble is selling an illegally modified vehicle that end up in a state which does enforce rules. The new owner fails and finds moded cats or pipes and other things the state then helps him track down the previous owner and helps sue the person who made the illegal mods to help current owner pay for rehabilitation.

AS IS does not protect you from emission fraud [the act of selling a modded car with a fradulent emission certificate]. Presenting a KNOWN modded car for emissions is attemped fraud, then fraud if it passes and you get a certificate.

Lying to the FEDS.

I had them on my 06 and the smell is negligable
I never really notice it, and nor does anyone else really.
I always just had some cologne in the car in case.

The power is more, and I never really heard the "rasp" on my car.
Watch out for those laws though, you can get in BIG trouble

I had high-flow catalytic converters then switched them out for test pipes. Could have saved $400 by installing test pipes in the first place.

Who pee'd in your Cheerios this morning?

Get the test ppes for more power, get the HFCs for more power than stock and less sound/power than test pipes.

How do resonated TPs sound compared to HFC?
And what's the difference between Ceramic and Metallic HFC?
The Berk Ceramic HFC is priced just less than the Fast Intentions resonated TPs. Hm.

After 22,600 miles one of the Kinetix HFCs developed a terrible rattle inside. It was embarrassing to drive. So I decided on an empty pipe. Nothing inside - nothing to fall apart.

Which HFC did you have? That shouldn't have happened.. Bizarre.
Well, rattle, or rasp? Pick your weapon.

To me it's either FI Res Test Pipes or Berk Ceramic HFC. Hmmm.
