Okay there's 500 pages of FI exhausts, and i need a little help...

Is there a comparo of sound with JUST the catback? (no HFC or test pipes)
- Non-Res
- 12" Res
- 18" Res

I'm trying to decide which to order.

I will be keeping the OEM cats so just looking to compare before i pull the trigger.

Thanks all!!
:tup:

Give Tony a call he will really be able to help you make your decision.

18" louder than stock, but not too loud with stock cats
12" will be a little louder and make you never want to roll your windows up again..
no resonator will be the loudest option for those NOT looking for a subtle exhaust...

Hope this helps

any chance of an updated list when u got a moment tony ..ta in advance~!

I don't suppose i could be greedy and as for vids of the preceding descriptions?
:rolleyes:

Please help!
 

So, I installed my system a few months ago, and I have some minor issues.
Let me prefice this by saying I absolutely LOVE the look, and sound of the system I chose. HOWEVER, I am experiencing a lot of secondary noise that literally makes the car sound like garbage.

Under moderate/heavy acceleration I am getting the common rattle in the rear area that sounds like its coming from the spare tire section ( which is annoying but not bad by itself). I am also now experiencing a quick more noticable and loud rattle in between 3000 and 3500 RPM's that almost sounds like a BB in a coke can vigorously shaking, which sounds like it's coming from right under where the headers would be. Also the all too infmaous VQ Hiss, for me, now isnt just on decel, but also heavy accel from 3 - 6000 RPM's ( ??Exhaust Leak?? ).

All things considered, as much as it kills me, I am thinking about removing the system and going back to stock. Before I do so, I think I may take it to a shop to have it looked at to see if something wasn't done correctly on install. All of these secondary noises are seriously driving me insane! Anyone have any ideas here? Or similar occurences?

Hiss under decel. - will be there anytime you remove the cats
Hiss under accel. - means an improper install or a leak
The car is know for rattles, and mine has a rattle in the hatch while stock.
Rattle near the header area may mean a bolt was not torqued down properly

If you can wait till Fri/Sat I should have my non-res CBE installed and could take a video.

The problem with your request isn't the availability of videos, it's the availability of the videos from similar equipment (cameras) and similar tests (revs, drive-by, etc). Every camera is going to pic up the sound of the exhaust a little different. Unfortunately the only way to get a really good comparison would be to have all three setups in front of you in person.

Video!!
 

Non Res CBE Non Res Test Pipes...

Idle with Revs, and a quick Drive by vid... Surprisingly enough, with the volume up a bit, if playing through something with nice speakers the idle with revs video is extremely close to real life. Check them out!

There is a really good video on the Fast Intentions site 370Z page. It's of a stock cats with 12".

As previously stated, trying to compare will be difficult without the same recording device used.

Tony is great at talking you through the right system based on what you are looking for.

this thread may be able to help you out!

well he heard non res. + long tube headers last Sunday, and will probably hear 18" res. this sunday if he comes :tup:

Don't forget to check the cross brace at the rear axle... I have a piece of industrial robber in there to stop that rattle... So check your clearance there.

grr my exhaust has been stuck at customs for 2 days, i wont be getting it till friday now. damn UPS

I have a rattle in the trunk as well around 2k rpms. Just can't seem to figure out exactly where/what it is. I believe it's just a interior panel reverberating against a body panel but just don't know which one it is to put something between them. It's not a defect, it's just resonance. Anyone have a similar noise and found the source so I might have an idea of where to start looking?

That's why I'm having difficulty making a choice. I love the sound these make but don't want the noise too high and with different camera's, it's tough to decide which sound I can take before I think it becomes too loud.

I have a similar noise. I removed every panel in the hatch area and it was still there. I haven tried it yet but I read that there is a counter weight on the hatch that can rattle sometimes. It's under the plastic panel on the hatch. That is one of the things on my list to check out soon.

But as of right now everything within 30 feet of my car resonates at all rpm. :D Hopefully not for much longer.

i get a bit of resonance rattle at like 2500rpm but it sounds like its more under the car than my hatch. whenever i put my car on the rack for its spring oil change I'm gonna check to see if that pesky heat shield isn't bent back enough. also see if its touching anywhere else as well. i highly doubt that since it's such a perfect fitting system but i just want to know where that sound is coming from lol :mad:

#473 is shipping today
 

... For all of you guyZ (and galZs?) who are counting the days for your FI exhaust to ship (...and I was one of you for the past few weeks till just a few minutes ago), Build #473 is shipping to me today... :happydance: :excited: :icon17:

Thank you Tony and the Crew at FI for all of your hard work and keeping the promised scheduled ship date...! :tup: :tiphat:

I am in the same boat. I think if you are worried at all about how loud is too loud then go with the 18". I am on the fence of whether I want to go with the 12" but don't want to regret it. So if I can't find someone local to hear one in person so I can hear it inside the car as well. Then I will probably go with the 18". Then it will be HFC or TP's. Decisions Decisions.

Anyone disagree and want to talk me into going with the 12" and I won't be disappointed? I want it louder than stock with a nice sound which the FI delivers. I just don't want to have any drone while cruising around town as this is my DD. So there lies my dilemma. Anyone who has heard both in person and can comment on how much louder the 12" is over the 18" please do.

I had the same dilemma.
Went with the 12" with stock cats. Couldn't be happier. No drone at all. Even the wife loves it. I would rather have it a little bit louder thank be disappointed that it's not loud enough.

while I agree, if you really are worried about it being to loud you could start with the 18" resonators and then add HFCs or TPs to get the volume you are looking for if you need more!

Anyone ever buy a resonated x pipe and non Res and swap em out when they want? Would tony even sell just the xpipe?

Good point, although I had no desire to mess with the stock cats.

someone posted up this idea on here before but I am not sure if they ever went through with it..

I had briefly discussed an x-pipe with 100 cell cats to get rid of the smell when I go long tubes. He seemed willing to fab up just an x-pipe then.

speaking of loudness, which one would be similar to amuse r1 exhaust??
non res? 12 ? 18?

I would say non res..

I am #475 and haven't got any tracking info yet. So hopefully that tells everyone were they are on the builds.

Everyone who is waiting, be patient.... It will be worth it in the end!

What was you're scheduled ship date? Trying to figure out if it shipped towards the end or the beginning of the two week window. Just trying to figure out if I should start getting excited yet. Mine is 4/3-4/17, so its' getting pretty close.

i probably wouldn't mind doing it. i like my day to day driving but sometimes you just wanna have a beast on your hands. definitely could of used it when i headed up to 2k12.

Mine is towards the end as I believe I was quoted the 18th-30th of March and its the 28th.

Tony I sent you a PM, get back to me when you get a chance :tup:

It was towards the end of the ship window...

What is the wait now?

My wait time was 10 weeks to ship - I do believe it is very worth it.

Here is exactly how our ordering process works. This is a template that I have created and the only thing that changes is the lead time.

"When you place an order all I require is a $250 deposit. I do not charge the remaining balance until your exhaust is ready to ship. At the time the order is placed I create an actual invoice for you. Then I will email you a PDF copy of that invoice to keep on file. Now all of my exhaust systems are hand built custom right here in house. I do not keep anything in stock. I am very busy and as of right now I am 12-14 weeks out to ship your exhaust once the order is placed! This may possibly be an over estimate, but I would rather under promise & over deliver! Now the lead time does not start until the order is placed and the invoice is created. Once your exhaust is built and ships I will email you your tracking number. I know the lead time might seem like a pain but it goes quick. We take a great deal of pride in what we do! You will receive top notch customer service and quality. I also understand how far you are and how crucial it is to get he right parts the first time. I ensure you that there will be zero packaging mishaps and everything will be as you ordered it. I just hear horror stories about other companies shipping the wrong parts all of the time!

Now I understand that the lead time might really scare you away. Here is what I can promise you. If our system is truly the one you want, the wait is worth it! Please do not force yourself to settle for anything less due to a faster turnaround time.

I think that I have covered everything. If you have any more questions or would like to place an order, please do not hesitate to call me directly..."

Thank you, Tony
