Thanks for helping with the test fit! Production has officially started on these! Group buy customers, I will be contacting you as soon as I get a better estimate of shipping dates!

FYI, I had my username changed from DDMotorsports to M.Bonanni for those who are wondering who the hell I am lol.

Is there any way to get dyno numbers prior to committing to the group buy? I'm very interested in this exhaust based on the vid...Thanks for any info you can provide.

The group buy is over unfortunately. The dyno results are here...

DDMotorsports: Berk Technology Cat-Back Exhaust

Basically the Berk Technology HFCs made 19whp and their cat-back exhaust made another 14whp on top of that. On this car, the first exhaust mod you do is going to free up the most horsepower so to have the Berk exhaust make 14whp in addition to the cats is awesome. I wouldn't be surprised if it made 20+whp on a completely stock 370Z.

Sounds great and the fitment looks really good too! I like how the tips are perfectly tucked under the rear bumper just like the Stock exhaust.

So the Berk HFC are making 19 hp and the cbe is making 14? I don't wanna sound stupid but this is the first time I've seen the hfc making more than the cbe.

Thanks for the information, sorry didn't search for previous...

gotcha, so you're saying you saw a decent change in the baseline as well do to the temperature change. I don't mean to be a pain in the *** I'm just trying to get everything straight for myself.

You have to just look at it as two separate independent tests. The temperature made a huge difference since it was probably 50 degrees in Feb. and 112 in August. I tried to make it as accurate as possible by doing a new baseline dyno before adding the exhaust so we have something to compare to and measure actual gains in similar conditions. So as far as gains go, the numbers should be pretty accurate. As far as overall peak horsepower numbers go, the temperature difference had a big impact. My peak numbers with the Berk HFCs back in February was 299whp. Power wise, nothing on the car changed between that dyno and the baseline I did in August, but the baseline in August was only 282whp average. So basically the only thing the temperature effected was the peak numbers, not the gains since both tests were done back to back with baseline numbers.

Awesome! Puts those gains into perspective.

I called Bryan at Berk at he's willing to do another group buy. We need at least 10. I started a thread.

GROUP BUY: Group Buy Second Chance Berk CBE!

puckshaw · 12-07-2009, 07:36 PM

Just when I thought I was set on the FI...

This really does sound fantastic. If those gains are accurate, this might be a real contender.

JakeZ34 · 12-08-2009, 12:21 AM

wow I was looking into the new CBE from Invidia from Lou @ Amplified. This has just changed the whole perspective. I love the sound of this CBE and being berk when I upgrade the HFC it'll have no issue with fitment whatsoever at all I bet. Need to know if this group buy is happening!
