I think it continues up to redline, but the engine and exhaust are so loud by that point that I don't notice the hiss as much. It's quite loud, though.

The only other thing I sometimes hear while not accelerating is a burbling sound between shifts at high rpms. I kinda like that sound, though.

I'm from the Myg37 forum, but I recently purchased the ART Test Pipes and am having some hissing sound that sounds very similar to this or pinging sound. I have the Gemini exhaust, and I'm not sure if it is the exhaust or anything is the reason....but I thought I would throw it out there for others to ask. I have a 2010 G37S 6MT Sedan. Any help would be greatly appreciated it!

The Invidia Gemini will do that with just the catback, but will be more pronounced with high flow cats or test pipes (no matter which brand). It's just the nature of the exhaust.

I had Berk HFC and my Gemini and I loved the sound. I wanted something deeper and throatier under exhaust, but still compliant with sound cruising. Mine don't have the dampening tabs but DID come with the RTV sealant. I'm assuming mine are the first generation ones though and like many of the people here said over the last 5 months they will come around nicely after 1,500 miles

We are conveniently heading to ZDayz on Tuesday, so that will take no time at all. I loved the sound of cats, but these do have some added power on the butt dyno....it just makes me not wanna WOT cuz of the sound. Next week when I add 3,000 miles to my car I'll post back. Sad to go from 8,600 miles to 12,000 miles over the next couple weeks

For what it's worth, my hissing sound was mostly gone after a couple thousand miles. If you have the old style gaskets you may want to replace those before you get an exhaust leak, though.

Did you end up using some type of gasket where the ART pipe meets the headers, or did you use permatext copper?

aadosx · 06-24-2011, 05:10 PM

Yeah. I think what you're hearing is just the sound swirling around and/or trying to escape the resonators? That was my guess.. I think I kind of hear what you're talking about but I don't really notice it.

Armonster what Exhuast do you have. What you have I believe is just rasp. Not the hiss people are familiar with on decel around 3-4k

I just installed my ART pipes yesterday after work. My exhaust sounds great. It's not much louder from what it was previously, but it's definitely deeper. Thanks Tony!!!

I've got the OEM nismo exhaust. I don't know whether the hissing is rasp or not, but I'd like to find a way to get rid of it ASAP.

I have the HISSING sound on mine too. It's quite annoying. I'm also curiously about how to reduce or get rid of it.

Which exhaust do you have?

I have the Boombop Shop CBE. It's a 2 piece slip in exhaust, no flanges. The exhaust sounds great with the ART Pipes. The hissing is noticeable below 4000 RPM. After 4K RPM its a beautiful sound.

Motordyne · 06-25-2011, 04:56 PM

One thing for sure, it very much depends on the exhaust it is connected to. Different exhaust parts react differently when connected to other parts.

AlphaSnacks · 06-25-2011, 07:05 PM

Just had them installed at Performance Motorsport. It literally took 20 minutes to get OEM cats out from the moment they popped the hood. The demon bolt aint sh!t for PM. I'm going to make a detailed thread when i get home, but in the meantime my quick impression is its louder than before but not much. The ART Pipes still need to break in so we'll see how they sound in a week.

Power, the top end has tremendously improved it simply hauls. The low end is brighter but i dont notice the torque increase as much as i did in my 350Z probably because it was auto. Regardless ive only driven it about 20 miles and all of it was highway. Detailed thread to come later.

AlphaSnacks · 06-25-2011, 07:58 PM

Err...I've developed some crazy *** tin-can rattle from what sounds like the driver side. I know we cut the bolt, I saw them do it. It sounds very metallic, embarrassing, and loud.

Any ideas what this could be? It's a constant metal noise. I've recorded it. Uploading the video now.
