Hks is more I think.

F.T. !!!! PWNS THE #@&%^&^*@ OUT OF HKS.
Correct me if im wrong but... you will only gain 1hp from HKS ?
LOL someone told me this before...

FI CBE Carbon Fiber Non Res. after 1 year.... still love it. ITS SOUNDS SO GOD DAMN AMAZING. NO lie NO joke. Smash it going through a tunnel... you will know what i am talking about. FI hands down. I cant express enough lol.

^^yea FI non res w/ carbon fiber is a soundgasm. I originally had 18 inch resonators and never heard any drone though (everything else basically stock).

I'm running the FI w/ 18" res and I LOVE it!

Sound is a deep growl. Zero highway drone.

I have FI Non-resonated with FI RHFC's and the only thing i get are compliments haha. They sound amazing and are LOUD! I just got pulled over today for having them too loud actually...

I had both I would go for HKS if I had to do it again so I voted for HKS.

For those who voted FI. did you really compared it with HKS or its just because have it?

I too have owned both and for me, its FI by a landslide.

1. Much better made, fitment is miles better on the FI. The HKS was a bitch to fit and it was never really straight. I had just as mediocre fitment on my ARK. The FI, I slapped it on, left it loose, straightened the flanges and it was 90% straight, had my wife and brother hold each tip and bolted it down. Install took me about 45 minutes(remove HKS and install FI)

2. Sound..HKS has a refined sound, I will give it that. But it is typical of an exhaust designed around the HH resonator, very deep and very "lobular", very similar to a ford v8 mod engine(4.6). The FI exhaust has a deep, growl too it, it is very Nissan, it is a 370z sound headed towards a GTR in a way, people like to describe this as "exotic".

While these 2 sounds are subjective and up to opinion, I felt the HKS sounded "garbled" with RTPs. It lost its clarity and refinement and just sounded loud. The FI exhaust can take whatever you throw at it, it does not change its tone, just gets louder.

With the CF cans, the sound is bit higher and louder. Call me crazy, but i just am not a fan of that quasi-v8 sound..

3. Customer service. Not a knock on HKS but a praise to Fast Intentions. If you happen to bust, say, ONE muffler, ONE flange or ONE resonator, you are either a) buying a new exhaust, or b) having a shop scrape something together to get you by. With a FI exhaust, you can replace one end or change your resonator settings or what have you. The product is backed completely by the hands that built it, you will ALWAYS have that direct pipeline to them, with the HKS, you are dealing with vendor-distrubutor-customer service, you will not be talking to the shop where it is built, nor am I sure at this point if these are all built under one roof to begin with.

4. Made to order. Get your exhaust, the way you want it. CF cans? Sure! No res? Sure! etc. Ans if you think it may have a bit of drone and too much volume, bam get some resonators put in. Or are you running TT and need some HFCs put into the x pipe because you are afraid of blowing out your cats, or cannot install cats, sure! The sky is the limit.

The only con is the wait, and it is a small price to pay. I derped around and bough a ARK GRiP(HKS knockoff) and then the HKS HP, sure I liked them, but then I still had my order in with tony, and decided to go through with it. Glad I did 100%..

IMHO, the HKS is likely the b est choice if you CANNOT wait, but in the end I wasted my money buying other exhausts and now I am happy with my 2.5" 18" res CF FI exhaust and it will be mated to my Fast Intentions TT setup. That exhaust was easily my favorite purchase I had made yet.

In the end, it is about what you want. Just sharing my experience. Yes, the FI exhaust will usually make the most power, but there is a lot more to it than that and that is what I am talking about. Listen to clips, reviews, get some quotes from the vendors. The best decision is an informed one.

370ZYZFR1,

It was great meeting you today and going veer all of the options. Thank you for your order. We look forward to getting your exhaust to you.

To all,

Thank you for the feedback and continued support. These past two years have been very taxing for all of us at FI and we appreciate the support and business more than you know.

Thank you, Tony

I guess he went w/ F.I., great choice!

I posted it somewhere else and not on this thread also. Forgot.

So guess who is number 925!! Me! Tony did a good job taking the time to walk though options and explain everything to me. Probably spent 20 to 30 min on the phone. As of right now I am going with the full cbe I may add the resonated hfc, just don't know how loud it will all be. If I do add the resonated hfc I will definitely do the FI ones without a doubt after talking with Tony.

Went with stainless 18 inch resonators.

Can't wait!!

Congrats man. You're gonna love the exhaust!

FI is the choice of many on this site, for just reason. Both are good exhausts. I prefer the sounds of the HKS (and ARK) over the FI, but, just like drone, it's very subjective. I think you'll be very happy with your FI set up. I think I may be the only Chicago 370z owner that is not running an FI exhaust :P

Ark grip v2. Its a HKS exhaust with an x pipe and bigger piping. And its similarly priced to the fast intentions exhaust.

Think twice. HKS has all the power and none of the drone, scraping issues.

I agree. FI Is a quality exhaust, just not as good as HKS IMHO

People ask/talk about FI because it is cheaper and more readily available. HKS does nothave the options like FI, but different strokes for different folks. And for what it's worth, people that have HKS are the ones that looked into both...

This is true. People like what they bought. Most don't make an honest comparison beforehand.

I will correct you. HKS gains the same as FI. And I go through tunnels with my buddies with their FI exhaust and more often than not, mine is determined the best sounding system... from them too.

This. People are voting for what they bought.

I am sure you will be happy with your exhaust. FI is a great system and a lot of people love it. I just don't understand why people have to knock HKS in order to feel good about their FI purchase! Maybe FI versus ARK or CNT would be a fairer comparison...

my :twocents:


(flame suit on)

Define best sounding.

That is very subjective. What may sound good to you and your friends, others may think is too loud or too quite or too something. I am not flaming, just saying that beauty is in the eye of the beholder.

I am sure the guy driving a Honda that sounds like a lawnmower thinks that he has the best sounding exhaust. But we know better......

I have not received my FI, and I hope I did not make a mistake, but since I have not heard it in real life I won't know until it is installed. Personally I was looking for something that is under or at legal sound limit (96 dBA)and yet sounds like a sports car. Not ear shattering, just loud enough to know I am not driving a minivan.
