Which Exhaust is Louder between these two??

Rooskey · 10-10-2011, 04:23 PM

I am in the market for a new cat back exhaust. I have narrowed my choices down between the HKS Hi-power and Fast Intentions with 18" resonators and carbon fiber mufflers. Which of these two exhaust are going to be louder. I have heard in person the F.I. but not the HKS. Thanks for the help

fast intention 12" res ?

Hands down the FI exhaust is louder but not annoying loud. The HKS is quieter at idle and during normal driving, it only comes to life at the higher rpm ranges and it's a sweet sound indeed. Either is a good choice but you have to choose whats right for you.

Check out AK's Video's

Finally Got my exhaust! HKS Hi-Power Ti Exhaust (many Pics, Video inside AK370Z)

HKS is more refined at cruise, quieter at idle. FI is all around aggressive and racey! I like the HKS personally but the FI is sweet too.

Thanks for the input. I think im leaning towards hks. I dont want anything to loud and if the hks comes to life only during WOT then thats the one for me.

HKS plus Berk's is the bomb! plus you don't have as much ground clearance with FI if you're thinking of lowering springs etc.

...but I am biased! lol. Truth is my friends have FI and it is nice but too much drone for me at cruise.

I think if you want good exhaust for a DD, go with the HKS. The FI has a nice sound, but a few people have complained about drone at highway speeds.

Rooskey · 10-10-2011, 06:14 PM

Yea I have heard the F.I. people complain about hwy cruising drone. Right now I have F.I. longtube headers and the factory Nismo cat-back. Im not looking for anything loud just a little less restrictive than what I have now. Who has good pricing on the HKS system??

+1 on HKS... the CNT is basically a :cough: rip-off of the HKS and I love it.

Here is where in lyes the problem: The HKS is smaller diameter tubing than our header collector as well as our CBE. This is why it is quieter however it will hinder the performance of your car with our headers! From a performance standpoint I strongly recommend against that combination. I can also tell you that combination will give you RASP. I have installed test pipes, resonated test pipes & HFC's with the HKS and every time I have heard RASP at 2500-4200 RPMS. The HKS exhaust plain and simple cannot support the exhaust flow of aftermarket forward accessories! I am not being biased, it is a fact. I have heard it with my own ears.

Now I can maximize your performance with our CBE and virtually eliminate any RASP. The 18" resonators will be the defining factor in this. Now if you want it slightly quieter than go with the SS mufflers opposed to the CF. Either way since you already have headers on the car, you will get some drone however how much is subjective.

If you have any questions please do not hesitate to call me directly...

Thank you, Tony

They will not fit given the design of the system.

Hey man, hope you find the setup you are looking for. I'll trade ya my exhaust for your headers if you are interested in that.

Haha no doubt man...I'm looking to go with a louder setup for myself. Honestly, I don't think they're is a better exhaust out there than the FI. I think you will be very pleased with SS and 18" resonators. The drone shouldn't be that bad with it and I know lots of people have went back to stock cats and were very happy with no drone.
