I only wish I started researching exhaust systems earlier on... Driving around with stock system whilst waiting for your FI order is no fun at all!

Ya i am use to driving a car with a exhaust, so i know i NEED a system ASAP. just kind of ballz to order one when i don't have the car.

but worse case i could sell my position to someone later.

I am officially in my shipping window......again :happydance:

And now the wait begins... Guess I'm #709?

when im in high gears low rpm i get this noise its not a rattling noise, an idea what it can be i check under the car but dont see nothing hitting

Around 1800 rpm?

Got test pipes or HFCs?

Even if you don't, if it's around 1800 rpm, that's just the VQ hiss. Normal.

just the cat and nah not the hiss more like metal hitting each other drive side

Put the car back on the lift... It's more than likely hitting the metal brace towards the rear of the car.

If you installed it, you may have slightly misaligned that portion. If you had a shop do it. Take it back and have them redo that side.

Do not my any means have them bang or hammer anything into place... Everything should fit as long as it is aligned.

Got mine in WOOHOOO.
3 mods
FI -CBE 18" stainless
FI -Test pipes resonated
Typhoon K&N intake

installed and tuned

Gained +- 45whp @ 7k rpm over stock.
Great solid torque gains esp @ 3k rpm

NO RASP.
and no the little gasp or breath the car takes after letting off a lil here and there isn't rasp.

Thanks for making a GREAT product and smooth transaction.
WORTH THE WAIT %100

What about drone or hiss? Any vids mate?

#650 Installed today! Love it! 18"SS Cans, with resonators. Excellent fit and finish.
No issues, everything lined up like it should. All hardware was new, gaskets and everything included....

I absolutely love this exhaust!

nice numbers dixnot!!

Ill try and get a vid up this week in and out of care.

anyone who has the 13 gismo deciding already to have this exhaust system as early as now? what will make you decide to shoot for it.. thanks!

Because you'll find that it is the highest craftsmanship & best customer service out there. It also produces some of the best power results as well. While sounds & style can be subjective, quality & service can not. F.I. Is a top notch hand built system & well worth the wait as some 600+ have found out.

Doooood read. There's 100+ pages of great info, dyno curves, pictures, videos, and testimonials. Stop being lazy and take the initiative. You will learn way more and come out with a much greater appreciation for what Tony and the whole crew at FI does.

actually i am on page 60 now and i just started last night. so. im not lazy. if somebody asks a question it does necessarily mean he is lazy.

what i am driving at is, if it just fine to do mods right away, exhausts per se, at a stage where the car is just under 1000 miles. besides good sound there is just a slight power gain over the stock Nismo (per member quote between pages 50 and 60) plus the weight reduction of at least 20 lbs. my point is, is it worth spending about 1500.

i was after for the new owners of 13 nismos thoughts why they decided to shoot for it right away at this early stage..

It will be fine...Scratch that, it will be better ;)

i like that... lol! :tiphat:

where is the shop sir? thanks!

[QUOTE=XwChriswX;2062743]Anyone with LTH's will tell you they are so worth it. :tup: Granted they aren't as cheap as HFC's or TP's, but cost doesn't really matter in the end to those who enjoy the sound and boost in low end after tunes. :tup:

i am just new with mods, just learning with techs.. my question is, is long tube headers has the cat converter with it? or you dont need to have HFC or TP be changed?

thanks!

With LTH's they will replace the stock exhaust manifolds and the stock cats. LTH's will not come with HFC's. You will have an Open exhaust system. :tup:

[QUOTE=XwChriswX;2145076]:tup: !! nice to learn!! that being said, would it become catless already? is it like having a test pipe? thanks again!

Yes it would, because the LTH's are taking the place of the Cats, it would be similar as if you were running test pipes.

not good for emission laws.. and LTH does not have resonators, do they? is it loud to have them c resonated CBE?

Correct, you will not pass emissions tests with LTH's if they do a sniffer test.

No, LTH's are Non-Resonated.

"Loud" is subjective. I have them with the 18" Res CBE with SS cans, and I couldn't be happier. :tup: It's a good balance.

nice.. interesting! what state are you from sir? no problems with emission laws at all? or can you cheat the test? :) or lax implementation in your area?

bottom-line, you are happy with your set up..

I originally was in AZ which did not require smog testing at all, and now am in PA. The county that I'm in does not require sniffer tests, and the shop that I go to for inspection builds dragsters so they understand modding and basically, if it's safe, it passes. :tup:


Yes, I am very happy with my setup. :tup:

sounds even sweeter!!!:tiphat: that would not be the case when i move to sunshine state i guess.. i might just stick with HFC then..

well, i appreciate your education to me sir.. thanks!

Cheers! :tup:

I thought FI made a HFC which could be installed below there LTH, similar to what Motordyne does with there mid pipe? Maybe its no longer available.

It's available, I just don't have it up as an option on the website. We use 150 cell Mil Spec cats. Our website is getting a face lift over the next month or so. In the meantime, I will try to post some pictures here.

Thanks, Tony

You really need to talk more about the 3 X pipe options not only on the first page, but on the web site also! so people do not have to dig through a 100+ page thread.

for example.
"The X Pipe has 3 options. Non Resonated, 12" Resonators or 18" Resonators. The resonators are strictly noise canceling devices. They DO NOT hinder performance at all. They are primarily designed to cut down interior noise resonance AKA "Drone"! The longer the resonator, the quieter the interior noise."

I believe you left out a very important part to this. is it fair to say the longer the resonator not alone does it quite down drone/interior noise but also exterior noise ???? beucase if thats the case its VERY important you put that in the details other wise it can be very mis leading.

I went with GTHause full CBE, please explain the best HFC u got for me. I'm interested in a HFC but please show y yours is better over berk, ERZ, stillen, magnaflow. Thank you in advance. Ohhh and how much. :D bump

It is ironic that you posted here. I literally just got finished sending you a pm about this information.

I look forward to hearing back from you.

Thanks, Tony

Great inquiry about what amount of noise cancellation the resonators do to the exterior sound level. That being said, this thread will be 4 years old as of this summer. This is actually a continuation of the original thread which was over 500 pages long. Now up until this point I really did not get asked about the exterior noise reduction all that often. Sure, I have been asked this question in the past but not enough to really make me think its a vital piece of information being left out. 99% of the time people are more concerned with the interior noise level over the exterior.

Now I can promise you after over 700 exhaust systems sold that nothing about our products are mis leading. I do understand where you are coming from though. In fact, I think you are on to something. I will update the website as well as the first page of this thread to try and give the potential customer as much information as possible.

As you already know, the resonators are strictly noise canceling devices. They do not hinder the performance at all.

Non Resonated
By far the loudest and most unrefined. Very exotic tone with a substantial amount of interior cabin noise. With stock cats I think it will be more than tolerable. With the addition of HFC's or TP's (unless you want it loud) I always recommend the 12" or even the 18". Outside the car: very loud and somewhat F1 inspired. The tone will be higher pitched.

12" Resonated
Right around 30% quieter inside the car and 15% quieter outside the car. As you can see, the resonators will effect the interior noise level much more than the exterior noise level. In addition, the 12" resonators will create a deeper, fuller and smoother tone across the entire RPM band.

18" Resonated
The quietest option out of the three choices. Roughly 50%-55% quieter inside the car over the Non Resonated and 25%-30% quieter outside the car. Again, you see that the resonators will effect the interior noise level much more than the exterior. Just like the 12" these will create that same deep, full and smooth tone throughout. This option is very practical for everyday driving especially if the stock cats have been removed. The 18" resonators will do a superb job in balancing the sound level back out.

I think that this covers it for now. If you have any further questions, please do not hesitate to ask.

Thank you, Tony

Thank you ,thats info i really needed to better see what option i would go with. after working with resonators in past i know how quiet they can make cars.

If i order an exhaust tomorrow, how long would the wait be approximately?

anyone with no res cbe getting vibrations noiises in the car when speeding a little

Current orders are taking approx 13 weeks
