The stock intakes on our Zs aren't anywhere near as limiting as the stock cats/CBE are.

I can only find 2 videos of berk cats and fi exhaust. None are taking off.

I got my Cobb accessport yesterday and I logged my air intake temps and they were only 8 -10 degrees over ambient temps so they do just as well as any aftermarket intake on keeping temps down. I put in K&N drop ins so Im sure they flow better too. I will logg my MAF but Im not sure what the numbers will mean, I need to PM modshack and see how the numbers shape up. The one thing the aftermarket intakes are doing that the stock isnt is they enlarge the MAF section a tad that tricks the ECU into adding more fuel or something like that.

The factory intakes are very efficient and are effectively cold air intakes since they source air from the same place that the G3s and Injens do (outside the engine compartment). They flow very well and are only a restriction after about 7,000 RPM.

True dat and above 7K rpms we are probably on the the down swing with power and should be shifting by then. I need to find out when the 7AT starts to loose power in each gear.

Any idea what the MAF numbers are trying to tell my dumb aZZ while Im logging them? Im not sure how to interpet the numbers.

I was looking for a real true dual exhaust. FI is way to go. My cousin has berk sounds good to me but I want something different. FI was there, and they have many options and the exhaust looks clean. Just wondering how my car is going to sounds with LTH, FI CBE. The intakes im not to sure about. Supercharger is calling me. lol

As far as this whole debate, I'm with Bolio. People are going to want to rep what they have on their cars in big part because they spent hard-earned $ and want to believe it was worth it!

The FI and Berk exhausts are so totally different IMO, that it really depends on what you want for your car. Do you want to show off something flashy/sexy? Then go FI. If you want more of a sleeper system, and don't care about any attention, go with the Berk.

Dyno numbers? Well, no two cars are the same. No two dynos are the same. There are so many parameters that influence dyno numbers, that it's not really possible to say system x is better than system y because dyno z said XYZ more hp/tq!

That being said, both systems are absolutely great in their own rights and I honestly don't think you can go wrong with either one!

Mike Bonanni posted before and after dyno results showing Berk hfc+cbe total hp gain.

"Berk Technology High Flow Cat/Cat-Back Exhaust combo is dyno proven
to make 36whp!"

I would expect FI also makes good hp gains.

No it doesn't make 36 RWH. Show me a dyno chart where the car has a baseline and then the HFC's and CBE installed at the same time with the gains in question.

Let's say for example the car makes 280 RWH (average on a dynoJet)
So show me a dyno chart where a car with Berk HFC's & CBE makes 316+ RWH! Produce the dyno chart and I will shut up!

I am not trying to stir the pot! Believe me, I have long cleared the air between Bryan (Berk) and I. We are good! However I am trying to set the record straight.

Thanks, Tony

I appreciate the support but you will get nowhere by just writing 4 words. Explain why you back us and you have had to heard both in person to make a proper assessment.

I am not trying to climb all over you but others will feel you are being biased without a description...

Thanks, Tony
