ARK HFC...still have "hiss"
 

Just wanted to put this out there. Nothing else wrong with the HFC, but the thing is they really marketed that they put a lot of research into eliminating the hiss that comes with aftermarket cats/test pipes on our cars.

Now I have never heard the infamous "hiss" in person other than on my own car, so maybe the ARK HFC hiss sounds better in comparison to other options. But for my car, when I am decelerating in gear it sounds almost identical to a car that desperately needs new brake pads. I am not talking about squeaky brakes, but rather I am referring to that scratching noise where it sounds like metal is scraping on metal. That's what it sounds like when I let off the gas, especially in 2nd or 3rd gear.

Can anybody else with the ARK hfc chime in?

So are u saying u have their new HFC and u believe u have the hiss ? Should be interesting ..

Yup, definitely think I have hiss

Not sure what you are talking about. I just went for a drive to locate this hiss sound on my hfc and i couldn't hear any. I think it'll be more helpful if you can record the hiss. And do you have the hfc with stock cbe?

No matter what aftermarket exhaust you put on your Z/G you will have some sort of Hiss its the nature of the beast.

+1...:iagree:

hmm interested in an audio clip

So basically there a waist?

anybody else has any updates on this? I'm very interested to hear more opinions

I will be installing mine next week, I'll add to the thread then. Team ARK, would you care to add to the thread as well?

Tried taking a video but it was very hard to hear in the video.

I want to point out that after making this thread I think I might have a tiny exhaust leak or something so maybe that is what caused the sound to start when I added the HFC. I am gonna get it checked out this weekend so I will update then. (I might have no idea what I'm talking about so someone correct me if this is unlikely)

Also I wanna add that it after listening to the sound more it has kinda grown on me and the more I listen to it the more I think it sounds badass rather than sounding like bad brakes which I said earlier. So if it is actually just from the HFC then I don't think it's a big deal

Dude I think I know what you mean. I just installed LTHs over the weekend and the hiss on decel and certain shifts was interesting and has definitely grown on me. I think it sounds really mean. And to the untrained ear mine sounds like the whistle of a turbo. I have had 3 people ask me since install if I was turbo'd. So far I am the only one I have seen with the ark grip 2 and fi lths

^audio clip, that combo sounds very interesting

Stillen HFCs and cat back exhaust installed Saturday July 7. Definitely has the hiss as well as a really nice burble and pop too. This has added a ton of personality to the car in my mind. I like a car that talks to you. On a roadster it sounds fantastic.

This is just a teaser. I plan on doing full reviews and using some nice recording equipment soon.
