Yea I know about the VQ hiss on deceleration or after revving the engine, but this hiss is just during idling when the car is stopped, that's the only reason it concerned me.

Hmm naw man if worse case scenario "could" be a leak but just check it out, I mean I don't hear a hiss on mine just that lil rumble it does when stopped at a light or parked. Maybe not tightened enough?

kfull 10-14-2013 05:18 PM
I had another listen when I left work and couldn't hear the intermittent hiss when idling at all. I did hear it when I got home. I have a feeling it's just air/air pressure equalizing across the x pipe connection since that section seemed to be where it's coming from. Does that sound like a possibility? Anyways I'm not worrying too much. I don't have any cel lights or anything. On another note, this exhaust literally makes me smile when I accelerate. It sounds so amazing. I can see where non res might be too much noise for some people, but I absolutely love it. It almost makes my ears ring :roflpuke2:.

Idling and just cruising at lower rpms it's not bad at all though. Carbon fiber mufflers+ non res sounds so good. I was looking at the connections on the old midpipe to where they connected to the lead pipes and I could see a decent amount of residue kinda melted on from the existing gaskets. The other end that connected to the mufflers was much more clean. Obviously this is from the difference in temperature at the different ends of the x pipe. They guys that installed it said they had no problems and it fit perfectly so I'm guessing it shouldn't be a problem. I linked some pics below. Otherwise, everything looks and sounds great and I can't wait to really get on it after I put a few more miles on it to break it in.:happydance:

Coming from owning a G37 and having an SS catback with 18" resonators...and later adding Resonated HFCs, I knew I would be running a similar setup on my Nismo.

I elected to go with a NONresonated Xpipe paired with Resonated HFCs and absolutely LOVE IT!!!!!! After completing the install Saturday morning, I wasn't even a mile away from my house and had already gotten 2 different cars give me a thumbs up...and then later another one at a stop light.

Will be doing a full write-up review on here as well as the MyG37 forum with incabin vids, gopro and comparable vids of a local G35 coupe that owns a non-res X with CF canisters.

I'm also rocking the front and rear fast intentions license plate frame so I'm basically a walking billboard for them:tup:

So what are all the different levels of "loudness" options for FI? From what I can tell 12" is middle of the road, between 18" and non-res. With(I'm guessing here) 18 and 12 at idle being close to the same, but louder when you accelerate.

Yea, non res is loudest, then 12" then 18" res. Even with 18" when you get on it, it comes to life and will turn heads. Then there's the difference between the carbon fiber mufflers and stainless steel mufflers. carbon fiber is higher pitched and slightly louder as well- "exotic" is a good way to describe it. stainless steel is a deeper tone. I've got the loudest setup now with non res carbon fiber and i love it.

Infamous 10-16-2013 12:02 AM
CF non res is the only way to go, kfull! I'm running the same with hfcs.

I thought it's the other way around. The carbon fiber canisters are deeper and louder.

/Angelo350Z/ 10-16-2013 01:19 AM
The length of the TPs only affect cabin noise, but both are just as loud from the outside.

No, carbon fiber is definitely higher pitched. You're right it is louder also though. How much louder I couldn't really tell you.

Hmm interesting... I had carbon fiber before but never compared with the ss in person so I could be wrong. But I thought Tony told me the carbon fiber is deeper?

snowsurfdirtx 10-16-2013 11:42 AM
I'm running ART pipes and non-res C/F.. I'll be posting a review and a few videos soon. My only gripe is the VQ hiss, but I don't blame the exhaust. I seriously can't keep my foot out of the gas it sounds so so good. Has a hint of 350z purr to it too. Even my roommate who is a muscle guy likes the sound lol

I have heard both in person (I have the CF version) and I can confirm that the CF ones are slightly deeper. Of course this is just my opinion I have no solid measurements to back my claim up.

Yeah that's what I thought. You could use my ears to confirm it haha... Tony we need to confirm on this! LOL.

To confirm...The Carbon Fiber mufflers have a slightly "higher" pitched" exhaust note. The Stainless Steel mufflers have a lower and deeper exhaust note. If anyone has any questions on this or anything else, please feel free to call me directly.

Thanks, Tony

Ah not so fast guys. I can confirm that the CF version is slightly deeper in tone. Although I am getting slightly horse from making exhaust noises for the last 3 months :eek::eek::icon23:

kfull 10-16-2013 01:33 PM
I think sound waves bounce off of carbon fiber more completely than stainless steel. Stainless steel absorbs a bit more of the sound wave as it hits, so it muffles the sound slightly better resulting in a deeper tone.

Sorry to say, but I think the manufacturer wins over you. Have you heard both in person? I specifically bought cf because I knew it was higher pitched and I wanted that exotic/European sound.

ZForce 10-16-2013 02:34 PM
Probably already been answered in the 199 pages of this thread, but I am not going to go thru all 199 pages.

So here goes, Tony, what gaskets are coming with the exhaust and F.I HFC's ?

Do I need to replace any gaskets ? Which are going to be reused if any?

speedfreek 10-16-2013 02:52 PM
I think the best advice Tony gave me when trying to choose between CF and SS is not to focus on the sound so much as both are very close and differs between each individual as to what tones they hear. Instead choose on the look you want. The beautiful sound and craftsmanship is a byproduct. Either way it is a win/win.

Totally agree!

For my part I went CF because I didn't want the cops following me to easily focus on shinny SS exhaust ;)

i believe the cats to x-pipe gaskets are reused along with the nuts

My apologies for not answering this sooner. Here is the breakdown below:

FI TP/RTP/HFC/RHFC: 2- 3 Bolt HR Manifold Gaskets / 2- 2 Bolt Gaskets.

FI TDX CBE: 2- 2 Bolt Gaskets / 2- 3 Bolt Gaskets

In the event that you retain stock cats in conjunction with our TDX CBE, reuse the stock 2 bolt gaskets on the bottom of the catalytic converters.

Thanks, Tony

Well said!

1) The Carbon Fiber is lighter than the Stainless Steel.
2) The Carbon Fiber will emit off a slightly higher pitched exhaust note. (Very minimal and most will not pick up the difference.)
3) The aesthetics of the Carbon Fiber will blend in more and look black at night. The Stainless Steel will attract more attention due to its polished mirror finish.

I always tell customers when choosing one over the other to make it about the aesthetics and take the other two reasons out of the equation. If you love the look of the CF mufflers, it is a great investment. If you are on the fence, save the money and go with the SS mufflers.

Thanks, Tony

critical 10-17-2013 10:53 PM
so i can't use my rear diff. jack point with my FI exhaust. i'm using a costco jack. i know other's have said you don't lose this jack point, but in my case I did.

I am good to go as I am not using stock cats and going with your HFC's. All new bolts and gaskets....yippee

Oh....and I am investing in the CF Canisters. Such a great investment. I am in line within the next 2 weeks for mine to be completed and ready for shipping. .... # 872

MeetZed 10-18-2013 09:23 AM
#844, 12" SS CBE!!! The wait is getting worse but its almost over!:happydance:

Do you mean 2 months ? I'm 850 and I'm looking at November 15. Give or take a week.

I was thinking the same thing. Looks like he had a typo ZForce is #827.

bchinfoon 10-18-2013 02:03 PM
Anyone in the current production range 818 - 822ish hear anything recently? I'm #821 and haven't heard anything recently about the status.

^^ ^ thanks guys !

True a typo. My first recollection was #827.....naw...that's too close to the number inproduction. Wow...what a surprise, I just bumped myself 50 spots forward.

Time to clear the garage !
