Yup, mine is the same way. I had my berk and cnt installed a month ago and it does protrude more than all the pics on this thread.

Thanks for the response. Maybe there are some manufacturing differences from ours to the ones online.
Thanks again.

They stopped making these with adjustable tips right? There's a pretty simple fix if they are adjustable.

This is the response that I got back from Bryan @ Berk a few days ago when I asked about installation and the tip length:

"I don't think you can install them upside down as I believe they would only go in one way. Tip length should be about a fingers/thumb width. If you have one of our older systems they are about 2 fingers width past the bumper."

So, the newer ones do not have adjustable tips, so they do stick out a little bit. Mine is one finger width past the bumper and the more I look at it, the better I like it.

Hopefully, I can get the HFC's soon to compliment the sound and power of the CBE.

I would definately recommend hfcs with the berk. The sound is very intoxicating and very addictive. The sound is more "raw"

I agree! They def compliment each other!!!

I am ordering the HFCs today and will put them on ASAP. It has to be ready for Zdayz!! Thanks for all responses.

I've already insalled the CBE and now I have the HFCs on order, so I am like a little kid at Christmas :yum::yum:. I have a question about the "Devil or Demon Bolts". How many of them are removed from the top and how many from the bottom? I am also looking at the diagram in the manual, and it looks like there is a combinations of bolts, nuts and studs :confused::confused:. Did you spray the bolts from the top or the bottom as well? I want to try and prepare mentally for the removal of these fasteners and try to anticipate all of the tools I will need as I will be using my tools, but a friends lift. It only took me an hour by myself to install the CBE, so I am hoping it is about the same for the cats. Lastly, are all of the old fasteners reused with the new CBE?

Jeeez, with all these questions, maybe I'll have my local Nissan Dealer do the installation :icon14::icon14:.

Any help is appreciated.

Bump...still looking for information on the demon bolts. If anyone has a photo of the old cat so I can see the fasteners, it would be appreciated. Really, all I need to know is what kind of fasteners are used and how many: bolts and nuts, studs and nut or whatever combinations there are.

Also, I called the my Nissan dealer and he said that they are not allowed to install the cats, because of any possible warranty issues that may arise in the future, especially when it comes to the EPA and the Feds.

There are three on each cat. Two bolts and a stud. The one that gives most trouble is the top one that is accessible from above. PB Blaster is the preferred loosening agent. But you still may have trouble. Just douse all three once a day for a few days.

My passenger side came out without a problem. Not so much for the driver side.
Here is my thread about it:http://www.the370z.com/diy-section-d...last-bolt.html


And here are a few more from the search function: Nissan 370Z Forum - Search Results

Thanks Dembflyr, that's exactly the information I was looking for. I guess that I'll have to pack the rotary tool into the "bag of tricks" on Friday when I attempt the install. I think tonight I will spray the bolts with PB Blaster and then light a candle for good luck.

Anyone lowered on a Berk CBE? If so, how many inches front/rear, and any problems with it bottoming out / scraping speedbumps?

There's a section of piping before that seems to sit so low on this thing..

I just ordered my Berk CBE. Should be here on Friday March 8, 2013. Really excited and can't wait to receive it. I did not go with the HFC's as I live in a really quiet neighborhood. I also want to see what it's like w/o the HFC's first. All the videos and sound clips about this exhaust look and sound fantastic. This is why I went with the Berk. I spent the last three/four weeks researching all CBE's for the Z. I had it narrowed down to the Tanabe and Berk and eventually decided on the Berk.

I see from reading this tread early on Berk had some fitment issues with some Z's. I would assume Berk has worked this issue out by now. Now that it has been a few years since they originally came out, I was wondering if anyone has installed this system recently and what their thoughts/comments are. My daughters boyfriend is a mechanic and will be installing the Berk CBE this coming weekend, Saturday March 9, 2013.

Can't wait!!:excited:

^^
I don't think there is fitment issue anymore , now all tips are adjustble (mine is).
I tried invidia HFC then switch to FI R-HFC and now running stock cats which I think is the best with Berk CBE . Now I'm thinking to try the ART test pipe and see.
Anyway Great choice.

I have the CBE and the HFC's that I installed last May. I did the CBE first, and then a few months later, I got the HFC's. To me, just the CBE alone was nice and mellow, but I wanted something that sounded more aggressive. That is exactly what I got after installing the HFC's. In total, it probably took me 3 hours to install both systems, but this was using a friends drive-on lift. The fit and finish was beautiful, and really compliments the look of the Z. The only issue was with the "demon bolts" on the exhaust manifolds. If you don't know about these bolts, I suggest you search and be prepared for the worst. Mine were not too bad, but it did take some work to get them off.

Once you are done, I guarantee that you are going to love the sound of the Berks. I know I do, and the stares that I get when I take off is priceless.

Good luck with the install.

I still think this exhaust is quiet even with with my test pipes, however once you open it up it growls beautifully! I have an older model with the oval tips, I would like to cut them off and get the round tips, the oval ones make it look too stock. I do not regret this exhaust one bit(got it used for a great price), once I get new tips it will be perfect! I have even had guys at work comment that my car that my car does not sound "ricey" it growls like a v8 haha.

Thanks. I am really keeping my fingers crossed we do not run into too much trouble regarding the dreaded "demon bolts".

Are you able to cut these off if need be? I could always get new gaskets and hardware I would assume?

I didn't realize that Berk changed the shape of their tips. Do you know what year they made the switch from Oval to Round? Was this the same year they went with adjustable tips as well?

No Idea, they still have a picture of both on their site.

370Z Dual 2.5" Exhaust - Nissan 370Z/Infiniti G37 - Berk Technology

check the pictures, far left is what I have, far right is what I want.

Yea, I doubled checked and I will be receiving the system with the Round Tips as pictured on the right. I am glad they changed to Round. I'm just a little concerned about them sticking out too far..........??

I got mine around this time last year when the oval tips were the standard and the round tips were only special order and extended out more to look better with the Nismo rear bumper. I had to pay an extra $100 to special order the Nismo version with round tips and very happy with it.

Got mine installed Saturday
 

I looked online at videos before making my decision on what CBE to go with. This is my first mod. I liked the sound of the Berk exhaust because although it sounds 38589397% better, it isn't over the top loud and obnoxious like some others and almost looks stock, too. Smooth and subtle. I didn't do the install myself. I had it shipped to a muffler shop near my house. It took the guy about 1 hr to put on. It sounds WAY better than the stock exhaust did. I love it!

Sunday I took it for a 3 hour drive out to the countryside. My fuel economy has increased from 23.2 avg to 23.9 per the computer. I'm thinking it's a little high because of the highway driving I did a couple of days ago, but I've put on over 100 miles in the city since and it hasn't come down yet. Maybe the computer made some adjustments and although I'm back to city driving it's still that efficient? I don't know, I'll have to give a few more days. But if it's more efficient then I'm going to speculate that I've more power too...

I installed the Berk CBE system last summer on my 370Z. I have the round slash cut tips. They do stik out further than I anticipated. Too bad they are not adjustable because I would like to push them in about 1/2 inch. The left side sticks out about 1/8 more than the right. Overall, the sound and quality are excellent. You will like the exhaust note over stock.

Finally Installed My Berk CBE
 

Received the Berk CBE last Saturday March 9th. I had them sitting in my living room. Every time I would go up the stairs I would see them, sitting there in their boxes. It drove me nuts.

My daughters boyfriend is a mechanic. He attempted to install the new Berk system from the ground with the car up on jack stands. He called a friend of his who owns a full body auto repair. He specializes is BMW's and Honda's. Well he has 5 lifts in his shop. He made a phone call and off we went to his shop. This shop was immaculate. 5 bays and the place was just perfect. I mean you could eat off the floors in this place. Everything was in its place where it should be.

Anyway, this was after hours so we were the only one's in the shop. I had to sit in the waiting area and was not allowed in the shop area due to liability issues.

When they were finished, they called me in the shop to hit the start button for the first time. First impression was, WOW :excited:

I am very pleased with the sound and performance of this exhaust. This is what the Z, IMHO should sound like. Deep and throaty with no drone. When stepping on it, it makes such a beautiful tone. The sound is really something to behold in person. Upon WOT, it just sings.....nice, very nice indeed.

Throttle response has improved, in addition to what feels like low, mid and high range improvement as well. The butt dyno don't lie.

Berk has done an awesome job. Love the Round Tips........I was told the Berk lined up just perfectly without any modification required. Using the lift, from strip down to new install, took all of 1.5 hours.

Now, I think it's time to upgrade to Berk HFC's. The guy who owns the shop said I could come back anytime to install them.

Very, very satisfied indeed.:happydance:

Got my Berk CBE to go with my Berk HFC's from FBNissan last Wednesday and installed it yesterday.

I just backed the Z onto my race ramps and went for it. I didn't jack the front up at all and access was better than I expected. It took a few hours with plenty of breaks.

Very nice quality materials and welds and the install was a piece of cake......except....the left (drivers side) tip hung down about 3/8" lower than the right and it also stuck out 1/2" more than the right. I loosened everything up and jacked up the left side of the muffler slightly and tightened everything down again. The tips are now at the exact same height which I'm very happy about but the left side still protrudes 1/2" further than the right.

I don't see a way to correct this since it's set by the length of the pipework so I will be calling Berk in the morning to see if they have any ideas.

BTW...This exhaust paired up with the Berk HFC's sounds absolutely amazing. I was worried about it being too loud during cold start and pissing of my neighbors (they already hate my big block 68 camaro with dual 3") but its not that loud at all until you get on it. This is exactly what I was looking for and it should have had this tone from the factory.

:iagree:

Good luck with yours. Mine did not have fitting issues. That is really weird. Don't know why yours would be any different? What year is yours? I see you have a Nismo. That should not make any difference however?

I have a 2011. I talked to a tech at Berk today and he said they see this from time to time and it has to do with bumper alignment. They are sending me a spacer to get it lined up so we'll see how that works out. I'm really curious as to what dimension is actually off, so I'm going to get under the car this weekend and take measurements of all pieces.

I still cant get over how nice this setup sounds. Today's commute was a lot more fun than usual. :driving:

I bet. I am now thinking about purchasing the Berk HFC's as well. Probably should have purchased them at the same time.

Best of luck to you. Hope the spacers do the trick. Keep us posted.

I live in Chicago......the weather here so far in March has been terrible. We are supposed to be in the upper 40's this time of year. We are barely breaking freezing for highs. Wednesday high this week will be 29F......WTF is that!!

It's killing me I can't drive the car with the new exhaust. Realize this crappy weather won't last for long, but it just plain sucks seeing my car in my garage just sitting there.......it's calling for me to drive her.....frustrating.

^ I hear you! Same weather in PA, drivng me nuts! I installed my m370 and hood struts today, it was in the mid forties so I said eff it and went for a drive, it was near 30 degrees when I covered it back up 2 hours later...sigh.

I was looking at getting the Berk CBE, does anyone know the weight difference from stock?

I think I've made my decision on the CBE and will be getting a Berk CBE + the HFCs. Now, just have to wait for that tax return and be 100% I want to spend it all on this. :icon17:

Now with some pics. Sorry, no before pictures, only the OEM exhaust lying on the ground. Man, is that thing ugly!!:eek:

I keep forgetting to make a vid of my Berk CBE. I recently replaced the Berk HFCs with ART pipes and the sound and power difference really refreshed the car.

The ART pipes paired with the Berk CBE definitely has more hiss under acceleration than it did with HFCs, but it sounds better overall. It is actually a tad quieter now too.

Do you still have the Berk HFC's? Are you willing to sell them? Just curious.

Thanks.

I always wanted to hear the ART pipes paired with Berk CBE . would you please make that vid ? thanks

Just finished installing mine and they sound amazing, it's just an eyesore that the drivers-side tip sticks out way further than the passengers side (which is perfect).

I guess I'm going to have to pull it off and try the mallet smack on the hangers to see if that pulls it back further... unless there are other ideas?

That's irritating. I am glad my tips were slip-fit adjustable. Are you going to get a shop to cut the longer tip off to correct its length?

I'll make a video later this week for sure

I'm going to try to bend the hanger. If not, I'm going to contact the vendor/Berk and see what else I can do. It's such an eyesore.

I finally made a video of the Berk CBE and ART pipes here

Thank you
