sound level for FI CBE
 

Good day fellow members,

I have a question for those with FI CBE. I just order a new set and debating whether there should be a 12'' resonator or non-resonated. I've done some research on the forum but I couldn't find any specific information on sound level for FI CBE only. So I'd like to seek advice from you.

1. How loud is non-resonated? (will it get on your nerve if you drive for a long time)? This is not my DD but it is the only car I got so it needs to take me everywhere.
2. I don't think I will get the HFC. But I may add in oil cooler, CAI (possibly stillen) and Turbo later on. If I get non-resonated, will this cause the sound level to go crazy?
3. I'm a newb to mods so I don't think I'm a good candidate myself on installations. Wondering if anyone know a good performance shop around Chicago area for me to take the exhaust in for installation?

Thanks a lot guys for your help!

The oil cooler and CAI will have no effect on the exhaust's volume. The CAI will add some induction noise. The turbo will make it quieter.

Hi Chuck,

Thanks! so CAI's increase will get canceled out by the turbo? do you have any suggestions?

If you're planning to buy a turbo, don't bother with the CAI. It won't work with the turbo kit.

thanks chuck.

Honestly, if a turbo kit is in the future, NA mods don't really make sense. Buy the catback and be done until you buy the turbo kit. If you buy an oil cooler now, you may have one that either is too small or in the wrong place. You could get away with buying a much bigger oil cooler and blocking off a part of it.

I originally had 18 inch resonators but switched to non res because I wanted more noise. I will say it is significantly louder than the 18 inchers, but I'm used to it and love it. I daily drive it too. It will definitely turn heads when you're accelerating, even just normally. Be a man and go non res:tup:

I have 12" res cbe only and it sounds great from outside but there is a drone at low rpm's and is loud in the cabin. Couldn't imagine how loud non-res would be inside the cabin.

hi Joey,

thanks for the feedback. I will see if there are more people can give feedback then maybe I can decide.

I have 12" res and I love them! I say split it get the 12" res you wont be disapointed not to loud and not to quiet just perfect...:tup:

12" is great on the outside but can be quite loud at times in the cabin. I wouldn't go Non-res. I am gonna combat mine a bit with some GTmat or a similar product once it becomes too much for me. But my exhaust is also paired up with ART pipes which made it louder.

but on the other hand. my current thinking on my Z is probably going stock on all rest of the exhaust system. so I may not have another pipe to increase volume.

Go 12" Res if you want a bump in sound add HFC and your reward will be more power. Intake I would not spend the money just drop in some K&N's and you are good to go :tup:

my gf is already very pissed on me modding the car:( not sure if that will be my next step. How big is the bump though? so if we compare FI non-resonated or 12'' to stock GTR exhaust, which one is louder?

Not one of my best videos but IT IS the idea. I got out of work and took a video with my Android S3 phone so hope you get an idea of the setup. My setup is Non resonated T.P with Non Res'd CF CBE. (Like I said NOT A high quality video but hope you get an idea, Its a Beast A$$ Setup!)

it totally rawrs!

I have the non res, with regular test pipes it is BONE RATTLING at low rpms. I sound deadend the hatch and put in ART pipes, it is now within acceptable limits, I considered going to 12" res but dang, the non res tone is 100% a head turner iand s redonkuously awesome.

The rattling is just between 2.5k-3k Rpms^^ but once tje pipes get a lil warm your good to go but I love my setup and WOT is just AMAZING! But I agree with Joepro our setups are TOTAL HEAD TURNERS ;)

so non-res has a different tone than with a resonator? Couldn't tell much from all the videos I watched on youtube. is it like a realized difference other than the volume?

IMO yes...I also have headers too...

Combat still going in my head:stirthepot:very hard to decide

I installed mine last night and did the 2 heat cycles this morning. This is just a short vid testing out some rear mounting locations for my external GOPRO mic I have been testing.

There is allot of road noise that gets picked up but I have some casual driving, some down shifts with S-mode, and the last little bit it probably running it up to 4500-5500 rpms. More to come when I get the audio worked out. BTW the mic is tucked up where the license plate lights are.



FI NON res HFC and CF TDX with 12" Resonators

Thanks so much for the vid. Do you think you can hold a clear conversation under the in cabin noise?

Yes the exhaust won't have much affect on being able to talk at cruising speeds. Once you get on it I think both you and your passenger will be listening to a very intoxicating exhaust note. It really does make these cars sound great.

I will says over the hundreds of video I have watched while I have been waiting really doesn't do the FI system justice. The crisp deep throaty sound it much deeper and stronger in person. Not harsh or deafening sounds really really good. Later this week I will see if I can isolate the road noise and delete it from the audio.

Thanks Rangerz for the video. I will have the same set up as soon as 850 arrives. Hopefully in the next few weeks.
And yes that sounds awesome.

I originally ordered the 18s but bought the 12s off another member just to see what the difference was. It seemed pretty minimal to be honest, it gives the idle a little more growl but i think the main difference is with the AC on. The 12s can get pretty loud. People are really aggressive when i have the AC on because it seems like im reving it out but im not:rofl2:
Guess that goes for any loud exhaust hah!

I really enjoy the 12s though, it brung up the volume enough for me to where its not completely ridiculous. I can still drive it keeping the volume down but whenever i want to make some noise it isn't hard :)

I can try to get a video in cabin with windows down and up maybe.

Does AC makes a difference on the exhaust tone? That's something new I heard. but video would be nice:) I've done a lot of searching on the forum but I didn't see much information comparing the volume of each FI exhaust. Perhaps this can be an informative post for everyone later on.
I think from all the videos I watched 18'' is too quiet for me. If 12'' and 18'' make not much difference. I will just for the non-res

I think the noise increase from the ac probably has something to do with the fact the car is running at a higher rpm.

damnit all to hell i forgot about recirculating........ fuckin exceptions......

ive never heard the FI 12 or 18 in person, but judging by vids are the arks louder?

bought non-resonated last week. Tony said its gonna sound great with the stock cats. can't wait.........

Not really the tone of the exhaust, the volume. Like Chuck said, higher rpm and more load if i am correct?

I will get some sound clips..im march or april... FML I hate PA.

Can not decide if I want 18" or 12" either.

So the tone is the same it's just louder...

My car has less then a 1000 miles in it, so I don't really know how it sounds when you accelerate quickly.

So 18" I think may be enough for me.

There are couple guys on the forum trading 18''s for 12'' or nons. so that kinda make me think I should get something louder.

I ordered the FI cbe with 18" res and their long tube headers that should be here january. i wanted a lot louder than stock but not obnoxious and as much power possible to make with an NA setup. I've only heard a few of the same setups on youtube and they all sound pretty aggressive.

I had 18 inch resonators, and switched to non res. I love the sound when I get up around 5-6k rpm, it sounds almost like dare I say an F1 car. Non res is quite loud, not gonna lie but it's awesome. Non res makes downshifts with srm sound epic.

When my buddy Greg rides along every time he says I quote "you have way too much fun with the rev match thing" I love rolling up to a stop about 40 mph pop in neutral and just give the shifter a quick move to the gaet for second gear, epic noise from this motor... here is a crappy vid from in the cabin z1 headers art pipes and non res FI.

And my dyno vid:

Holy crap your Red line is at 8k!? Any set backs from that?? And very nice looking Z man sounds Beast!

Its cuts at 7500, it has a quick moment of rasp at 2k but the art pipes clear it up quick.

7500, hmm weird it clearly Goes to 8k on your vid but either way very nice and yea I know what you mean that lil rasp between 2600-3000 is a lil annoying but ehh it comes with the perks so can't complain :tup:
