I have never seen anything like that. What is so special about it? I can't understand the translation at all.

Looks like it has backpressure bypass tubes. At low rpm it gives you backpressure so you preserve low-end torque. Then past a certain rpm it slams shut so you have the benefit of the free flow.

Yes. It'll help with NA as well, but FI will benefit the most from backpressure-adaptive exhausts. I seem to recall seeing an HKS exhaust with a similar setup at one time (for a different car - possibly the 350 or s2000).

With shipping to the US, what will the total cost be in $ ?

I know a lot of you have been wondering what the Nismo Catback with Berk HFC's sounds like, well here you go

I can tell you that it has made a huge difference in sound (quality and volume)
The car still sounds pretty normal while cruising, (Zero Drone) but when taking off normally you can now here the exhaust note. And at WOT, wow!!
It's not super loud by any means, I think some people would still say that it's mild, I'd say that if it was between mild, medium, or loud(race) this would now be a medium, where with just the Nismo catback it was mild.

This is exactly the kind of tone and volume that I hoped for when I first installed the Nismo, but I was pretty disappointed. Now it has really come to life. IMO it should have sounded like this from the get go, but I guess Nismo engineers were forward thinking, knowing that a lot of people would probably install HFC's of some type and eventually end up with this result.

There is no question the car is breathing much better, the throttle response has improved and with out a doubt it it quicker.

Amplified Motorsports in Monterey Park did the install in about 2 hours, thanks Paul, Lou & Jet!!
Oh, they also installed my cross drilled/slotted rotors at the same time, so the cats didn't take up the whole time.

Ok, here is one more, launched at about 4K, and then did a mild drive by under normal RPMs

TacoZ · 04-26-2009, 02:18 AM

Holy crap! That's exactly the sound I was looking for! Not too loud but just loud enough at WOT. If it's true that there is zero drone, then I am definitely buying the Nismo Exhaust with Berk HFC! Thanks for the clips!

Yep, zero drone, sound pretty much stock while cruising, just a pinch more volume.

350Z

S2000

Hopefully they'd do a set for the 370Z too!!!

That sounds great. I just wonder what the power comparo will be like when you take a car with HFCs/Stillen and HFCs/Nismo.

semtex · 04-26-2009, 07:33 AM

Sounds good. Any plans to do a dyno?
