:icon18: that's the x-pipe which is probably the important one cuz it has the most gains and sounds the sweetest :drool:

go put in your order or :gtfo2: :tiphat:

The only thing I do not like about this exhaust is the weight. Everything else looks great.

more weight over the rear of the car is definitely better than more weight over the front. Unless you are a full out race car you won't tell the difference of a few pounds.

I agree. I wish we had a weight for the x-pipe.

I saw it posted earlier in the thread, and was kinda glossed over so I wanted to see if I could get a more in depth answer about this cause it was something I considered...

Me myself, I like the looks of the / \ style cannisters that FI makes, but after listening to the Berk video's, I like the sound alot more. Which, looking at the numbers, they are relatively close as with most exhausts, so for me it comes down to Asthetics. Earlier it was mentioned that Berk went with a = design versus the / \ because of the aerodynamic lift created from the space in the / \ design.

However my original thought process was wasn't the point to make as few bends in the system as possible, for that 'straight through' power? It seems as if this puts alot more bends in it to make the = pattern work? :confused:

Do not get me wrong, I am not bashing this system at all, I really am growing fond of Berk products :happydance: and just like clarification. I will probably get this setup of HFC + CBE as soon as theres more vids of people driving with it. Dyno's are good, but unless I'm on the strip (which I'll be inside the car) I won't get to know what it sounds like to the outside world.

straight through with the least bends as possible is what people won want a turbo in the near future will look for. More bends in an NA car isn't going to affect the overall horsepower as much, and it will likely gain a tad bit more torque due to a tad bit more backpressure.

keep in mind a tad bit is something you will never feel on the butt dyno. The difference isn't going to be noticeable between the /\ and the =

Ground clearance I believe was one of the reasons berk went with = as well, although it appears FI got everything under there with enough clearance.

So you are saying if someones looking to go ST or TT later down the road, this isn't the kit to go with? Cause my goal is right now, do everything from HFC's back, still a little unsure about headers cause I've been reading the posts here, dunno if I wanna tackle that myself. And I'm looking at doing a TT setup (when it's whithin my budget lol).

The second video is the same exhaust as the third.

The true dual was from the cats back, with no x pipe, y pipe, or h pipe. No pics of it, that was the mock up system they made just for fitment.

to be honest, if you go with a twin turbo kit you are going to want to do a full custom exhaust. The piping diameter could use a slight increase over what is out currently with boost, and you likely won't want cats because legality gets thrown out the window with TT's.

If TT is in the NEAR future, I wouldn't spend money on an exhaust until you have them ready to be put on, then you can do it all right, at the same time. If it is far enough out in the future, you may consider one of the exhausts to hold you over for sound and a little bit of gains until you do so.

Thats my plan, it's gonna take a while cause basically what I wanna be able to do is drop it off at a shop, say I want the engine rebuilt, TT's added, and whatever else is nessecary (electronics, dyno, tuning, etc.) all at once, so when I drive it away the GO is done and I can focus on the SHOW. My Income to Enthusiast ratio is like 1:7000 lol So it will take a while to save up all I'll need to cover that cost.

I'm assuming this exhaust will be fine with an S/C as they don't rely on free-flowing exhaust like turbos, correct?

It will be a good addition to any FI in my opinion.

i wonder if berk will make headers..seems like stillen is the only choice...the guys at s2ki seem to like their ceramic coated headers by berk

Just wondering, what is the outer diameter of the stock exhaust?

I have asked them about it, but the problem is the stock manifolds are very efficient so aftermarket ones don't gain a whole lot of power. Not to mention the install is not a DIY for most customers so when you add the cost of headers + the cost of install vs. the performance gain, its not really worth it for most people.
