From what I've seen from My350Z site, it looks like the gains are pretty good.

And you can see more here:

Although their price seems a tad bit more then I'd like to pay... The MSRP is $549.99, but they're selling it for $474.99 from their web site. I wonder how much did Joey pay for his?

 

Fast intentions can get you HFC's as well. call tony,
818 882 2788

 

480 for the Exhaust system for our car??? If thats true I would glady pay that much considering the cost of the Stillen Exhaust.

We all have to remember what we are buying here because of the fact its two mufflers....well two of everything.

Plus....it sounds sexy.

 

I think that's the cost of HFC, exhaust should cost more,

but if that's the price of the exhaust, that's a super price

 

No, that's only for the HFC from Berk's Technology.

 

Ahh, still with the gains associated its not that bad.

But what of the exhaust, what was the price for the prototype if he shared it?

 

The price for the prototype will not be the same as the price for the production version. A good indication of the group buy price is the recently released G37 version which ranges from $875 to $1075. From what I've read, that puts them hundreds less than comparable cat back systems. I'm guessing the G35 cost will be close.

 

Okay, so, I'm reading these responses and I must say, the FI CAT thus far looks and sounds fantastic.

For clarification purposes, Terry's ride is using the FI CAT, which is obviously using the OEM catalytic converters. Whereas, Joey's ride is using the Berk Technology HFC converter, which replaced the OEM version.

 

You are correct.

 

Rear Hub Set-up:


Dynapack Test Set-up:


Here is the resulting comparison showing the average of 3 runs with FI exhaust vs. the average of 3 runs with stock exhaust. All runs completed within 2 hours to eliminate environmental variables.

nice gains,
man, i'm colorblind, can't tell which line is what and when they crossover...

 

Terry did you get the sebring mufflers on yet?

 

I hope our cars can get 300bhp after a few bolt-on mods with a reflash.

BTW, I like what I'm seeing here!

 

They graphs are superimposed.

The torque curves on the left show the peak has increased 5.5 ft-lbs and shifted slightly to a higher RPM. Peak torque comes up around 5400 RPM instead of 5200 RPM stock.

This makes sense since the FI exhaust is less restrictive.

Also remember ... my car is a 5AT. You guys with a 6MT should do better with less drive train loss!

 

Nope ... the Sebring mufflers will be on when I pick may car up on Saturday. We'll be sure to take more pictures.

The Sebring and Magnaflow mufflers are similar in construction, so the resulting power / torque gains will essentially be the same. I'll let FI answer if anyone wants to know about muffler design.
