Fast intention exhaust owners chime in
 

I am considering getting this exhaust but the only thing holding me back are complaints about drone and annoying vibrations from the exhaust. For all you who experienced this exhaust, how bad is this? I already know this exhaust sounds amazing but I'm going to be using my Z as a daily driver so I dont want to regret getting it. Btw I want to get Stainless steel 18".

It's not bad at all. I would highly recommend it. Even with HFC's it's fine. There is some drone and vibration at certain RPM's but not annoying and hardly an issue (for me). Remember, it's a performance exhaust. If this bothers you get a something tamer like a Stillen or just stay stock. LOL

:iagree:

The exhaust itself should be fine unless you start adding HFC or TP

I felt like there was some drone in the 2,000-3,000 RPM range with the 18" CBE and stock cats. I could deal with it but it would give my gf (who has more sensitive hearing) headaches after long drives.

It didn't help that the highway driving we did included a lot of hills and mountains, so the car was constantly loaded in that rev range.

I don't think you will regret the exhaust. It sounds amazing. And if for whatever reason you don't like it, it's not exactly a hard system to sell.

there is a slight drone, I actually have m4a1's exhaust on my car. The drone isn't bad at all though, considering the lack of sound deadening this car comes with. I love the sound, and I may even go a tad louder.
I'm running the 18" res w SS mufflers with stock cats

I really don't notice what I think is drone, and I have the 12" resonators/SS mufflers. There is a "hum" if you accelerate slightly in 6th gear between 2-3k rpms. But as soon as you resume cruising it goes away. To me, this is nothing. I've had exhausts that droned across a wide rpm band, with no escape (decelerating, accelerating, downshifting, etc. still produced drone).

I get a faint vibration in the dash at times.

None of these are issues for me personally, because the exhaust sounds sooo good. An angry growl at lower rpms, a scream at 4k and above, and completely well behaved at idle.

I love this freakin thing!

Before I added Non-Resonated TP to my FI Non-Resonated CBE I had no drone or weird vibrations. Its a much different story now.

I have had mine for a week. 18" CF. I love it. The car is my DD. I hate having to park it because I don't get to hear it any more.

Had mine for a couple of months now and all I can say is awesome! She sounds like a sports car now, which is what I expected from the NISMO initially. If I had to do it all again, I would just go with F.I. from the start. I actually traded my Berk GB#2 slot for the F.I. TDX that I have now. Next up LTHs baby.

I have the CBE no resonators and the LTH and love it. Yes there is drone but not so loud that you can hold a conversation. It sounds how a sports car should. I had just the CBE for while and it was perfect but when I added the LTH the tone was the same just more raw. My setup isn't for everyone but the CBE in any form (non resonated, 12", or 18") will make you very happy. Tony is the best to do business with.

Steve, here is a vid I dug up featuring your setup so the OP might be able to get a listen.

:icon18:Was there a sale on Z's at Kohl's that day?:icon17:

man I think what you are asking is more of a personal preference, I have the same setup which you are looking at and its in FS section.

There is a drone/vibration which rattles the car under normal cruising from 2200-2700rpms in every gear, it does rattle my doors/dash or other plastic things at different time and that also when you are pushing the car ery slowly if you push it hard the I think its not that much there......... thats the only thing uncomfortable which I personally feel for a daily driver, rest its amazing. I am trying to change but I know I wont get any other exhaust which make your car sound so sick. Coming to your question how bad it is? its not bad at all if you are okay with this little issue :tup:

Haha I totally forgot that video existed.

Every Saturday @ 10AM.

Now offering Mustangs, too! :bowrofl:

Drone is subjective and everyone will perceive it differently. We have 5 different CBE options for all different sound levels. Some are loud and some in my opinion are quiet. In addition I have sensitive ears so I am not deaf by any means. As far as a vibration you might feel a slight one during certain RPMS through the gas pedal. But very slight as long as the exhaust is installed correctly. The exhaust is very rigid once installed and nothing is close to the floor so unless it is rubbing on something you will be fine.

I have installed over 60 systems myself and never had an issue and I have no doubt that you will love it! Whichever options you decide to go with.

One last note, if you have any questions please do not hesitate to call me directly...

Thank you, Tony

Quick Question...
 

(setup ordered: FI CBE non resonated, non resonated TP as well.) I ordered my FI exhaust last week. Listening to vids and doing my research, I was pretty certain I knew what I wanted. I talked to tony and solidified everything over the phone. My initial thoughts were that I wanted to really wake this car up. Reading all this drone rattle business didnt really get me worried but I figured why not take the opportunity to ask you guys, since you have it installed already, is it anything Im going to need earplugs for? I like a loud exhaust, but I dont want to be droned out of my car (which from what I read and saw I dont think will be an issue.) However like I said better safe than sorry... From what Im expecting Ill have some drone but minimal, and minimal rasp... anyone care to jump in here and fill in the blanks with some solid experience?

the only time I get any sort of drone is when the engine is under load... going up inclines, or slightly increasing speed... as soon as I settle at a speed... the sound is gone. I don't have any vibrations. I have the ART pipes with the F.I. CBE with 18" resonators.

I can attest to calling Tony, being a solid solution to any questions you may have. We are all busy at times, and not always able to read and respond to PM's and such, as timely as we would like. I called Tony, and he sounded busy, however he didnt hesitate to take the call in his office and answer all of my questions and concerns; and walked me through ordering my system. Mad props to Tony and Fast Intentions for a job well done!! :werd:

The one thing I wanted to avoid, was installing my system and wishing it were louder. The one great thing that I see so far coming from F.I., is the fact that they have many sound options for their systems from extremely refined, to a throaty race exhaust. I'm sure Im going to love the system I ordered once installed!... I CAN NOT WAIT!!

i'm sure you will... my issue here has always been is it's hick country and if you drive the loudest jacked up POS you'll be fine with the cops... have an import with even a mild set-up and you'll be pulled over. However, turning 33 this year definitely has made me more tame and for me the tone is excellent when I want it to be, and mild when I want it to be.

I currently live in Philadelphia, and cops are very lenient when it comes to exhaust; unless your running straight pipes on an Olds 442 LOL. And like I said from what I saw on Youtube, Tony seems to have a pretty solid product that like Methodical said, is excellent when he wants it to be or mild when he wants it to be... I spoke with another forum member (mtaxelson) who went with the resonated system and he stated after the system broke in and quieted down, it was the perfect note for him but borderline quiet for his liking, and he wasnt sure if he should have gone with the 12" resonated system over the 18". So worst case scenario, I install the system and it is in fact too loud, I can always throw on the stock cats. . . I'm pretty sure Im worried for nothing here... So far it doesnt appear that anyone running the non resonated CBE with the Non resonated TP's has deafening drone, and that is really my only concern here.

I said it before and I will say it again. I still get hard every time I start it up! Take it out for a spirited drive and that's all she wrote.

HAHAHA... Subtle my good friend! LOL :rofl2:

i have fi with 18 inch resonators and stock cats. there is some drone and its a bit loud but i like it. would get the 24 inch res. if i had to do it again

yup
 

You are the first person I heard say that the 18" reso system was loud. But like everyone said, its subjective.

I'm in the same boat. I bought the F.I. 12" system and while it sounds great on the outside of the car, the drone inside around 3K RPMs is terribly annoying. I also get the rattling sound from the drone. I also think the exhaust tone is a bit too much for my neighbors. Any suggestions to tone it down some and get rid of the drone sound in the cabin?

Switch to 18" resonators. Won't probably change it much on the outside but should reduce drone inside according to FI.
Also, tell your neighbors to :gtfo2:

FI 12" CF CBE with Motordyne Art pipes. Some drone but not overly unbearable. Interior and exterior sound is top notch. Just took my Z on a 6 hour trip and I had no issues with the drone

I'm trying to see if someone wants to swap with me for 18" ones - http://www.the370z.com/parts-sale-pr...esonators.html

Do the ART pipes really help with the drone noise? I don't plan on getting CF canisters.

I love the sound of the exhaust but if your lowered I wouldn't do it. I have the 12" resonated FI and the passenger side rear can got torn apart by something that went under the car at highway speeds at night. The cost for one rear can is so expensive I decided to just go with the Greddy EVO3 exhaust now. Just an FYI.

The FI exhaust doesn't hang any lower than the stock exhaust.

FI System Ordered.......
 

Hmmmm, never saw all the chatter before I decided, but I ordered the HFC with res, CBE with 18" res, and CF cans......I am chomping at the bit to get it, but I am trying to think of something else.....yeah, it's not working......

After hearing ALLLLLL the others, this was my favorite, so hopefully time sort of flies.....Stillen, AAM, but the FI has me practicing patience..... I am so not patient....

I'll update everyone with the video and outcomes....

3" catted version here chiming in. There's a touch of drone just over 2k rpm, but it is gone by 2500 or so.

The piping from the cats all the way back to the axelback, no it doesn't hang any lower then stock, but the Round Muffler cans...yes indeed they do.

love the sound running 18" resonaters w/ HFC. little drone at low rpm there is constant hiss but use to it as well

It's not how low but what shape it is. I can post a pic if you'd like to see. It will change a few people's minds. I did measure at that location under the car and that area under the car is at a lower point then the stock exhaust in that same location. Overall it isn't lower then stock, but always read between the lines.

Still looking for some help with this. Thanks.

Still looking for some help with this. Thanks. Will CF canisters help with drone and cabin vibrations?

From what I hear the CF mufflers give a even more unique sound. If I could do it all over again I would have went with the CF, at the time I felt it was a little ricer.
