Haha I see your point - part of the reason we all get exhausts is so we can hear them

However, IMO hearing a constant drone (with no difference to the outside noise) would start to bug me after the first few days/weeks/months..

The 12" is definitely a little louder than the 18". I have the 12" and have never had any drone at all.

Straight copied and pasted from Fast Intentions website...

"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."

Just got back from Tony's shop and i must say he does one hell of a good job. The exhaust with 18 inch res gives a really nice sound to my nismo. It's a touch louder than i had expected, but it's a nice deep sound. It also feels like a bit better power, just from the butt dyno.

And it's lighter to boot!

Realale · 09-18-2012, 06:48 PM

Oh yea

I have an 18 inch resonator and CF cans with FI high flow CATS. With out a dought the finest craftsman ship ever. I love the tone for short drive and performance but it did get loud once it all warmed up.

Footloose recommended ART Test pipes and they made a big difference in lowering the sound and upping the bottom end torque. Also sound deaden the crap out of the car adding 30 pounds.

All in all Sophie is my daily driver, I drive hard but not hard enough to use the performance that comes with the hole package. I'm not rich and can't spend money on track days every month, I wouldn't mind trying something quieter.

Also would like to install spec-r springs but the pipes hang lower that most exhausts I've seen. I scratch them now going over speed bumps, the spec-r springs would destroy my exhaust.

Hey you got any videos of your FI 18" CF Exhaust and the FI hi flow cats? I'm looking to get the same setup, how loud is it? Any info would be greatly appreciated.

Hi all,

I have with me (in combination with the STILLEN supercharger) installed the following version:

F.I. TDX with 18 "resonator
F.I. HFC with resonator

Without the HFC no dron in the inside. Outdoor deep and loud. A sensational sound!
With the HFC is a dron in the inside at 2'000 r / min. Outdoor deep and very loud!
My neighbors are in the kitchen the dishes out of the closet!

With a standardized measurement, we measured 108 decibels at idle speed 900 r / min!

I must say that the supercharger kit increases the volume a bit!

Enclosed is a film (from minute 2) where you can hear the whole thing.

Will make a video to night. I still have HF FI Cats but there off the car. It was significantly louder with them on. That video AXMEA posted is the same tone and sound. Quiet in the cab until its under load. I turn up the radio..

I have been looking at the HKS exhaust AK put on his. I would trade the system for a decent used HKS.

There's sometime a 370Z on the road in Switzerland, which can forget the clock and cheese ....

Super I could help you a bit..
