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.

The first exhaust mod you do on this car is going to make the most gains whether its HFCs or a CBE. I dynoed the Berk HFCs with a completely stock exhaust system and made 19whp. If I had already had the cat-back on the car the gains wouldn't have been so high. On the flip side, if I dynoed the CBE with stock cats instead of the Berk HFCs, those gains would have been more than 14whp. Am I making sense?

Yea I get what you're saying. So you're saying that dyno chart in the other thread was roughly 19 hp less than the 280ish number before you put the HFC's on?

I did a baseline dyno of the 370Z 100% stock back in February. Then a few days later dynoed the Berk HFCs while the rest of the car was still 100% stock and the car made 19whp over the baseline.

Fast forward to August. Since Vegas in February vs. Vegas in August is a massive temperature difference, I did another baseline dyno of the car, 100% stock with the exception of the Berk HFCs. Then I did another dyno with the Berk CBE on and made 14whp over that baseline.
