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.

:iagree: This would be awesome!!!!!! :tup:


EVL370...If you want a louder exhaust, then I would say go with the F. I. but you would need HFC's paried with it...The one's that I've heard are paired with HFC's and seem louder than the Berks that are paired with HFC's...

I personally like the sleeper/stock look, with a nice exotic and intoxicating sound...So I chose to go with Berk

It sounds like an exotic car mixed with the deep sound of a muscle car. It sounds unique and extremely good!

I'm getting my Fast Intentions exhaust with 12 inch resonators and carbon fiber mufflers installed tomorrow so stay tuned for video and pics.

Trust me, you will be more impressed with the Fast Intentions in all categories. :tup:

Have you heard a Berk in person? No? Then how can you make the statement above?

I can promise you that the Berk will be louder/more aggressive :stirthepot:

Is there data to support this? I have not seen any data regarding gains from the Berk CBE. Anyone?

Great writeup Matt

Indeed and a +1 to Matt!

Was it mentioned that the FI cbe is about 16lbs. or so lighter than the Berk?

He might not but I have. I have heard Minicobra's in person while I was standing right next to Bryan from Berk!

I WILL NOT say anything negative or descriptive about the Berk because they are obviously my competitor and that is not professional. What I can tell you is (from the outside of the car) the Berk is not as deep or smooth as our exhaust system. Do not get me wrong, the Berk sounds very nice however I feel our system has a deeper, fuller exhaust note. As far as looks that all depends on the person buying the system. Ours has a very aggressive look that in IMHO fits the car well. The Berk has a much more stock sleeper look to it. Some people want that. I do not fault them, that is why everything is subjective...

Thanks, Tony

First and foremost, our system doesn't DRONE at cruising speeds. I have sold almost 130 units in 8 months and I can count on less than one hand how many of my customers comment about drone. Yes, it can be a bit much for some and on the flip side some call me and tell me it is too quiet. On the 7AT we do get some drone while accelerating up to speed through the gears. In my opinion it is not an issue and we have many options. This is what makes life great, options to choose from so everyone is not stuck with the same thing!

Thanks, Tony

I do not know the weight of the Berk but our system ranges from 10 lbs lighter than stock to as much as 20!

The lightest option would be our straight through X with carbon fiber mufflers!

Thanks, Tony

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
