was a guess of mine

I was thinking the same thing, much better "flush" look. Minicobra? If not, would love to know the spacer amounts.

John

Power and weight numbers soon please!

Exhaust is looking great. I look forward to your next update!

Berk Technology is coming up to Vegas this weekend for Formula D and if my exhaust fits in the trunk of their BMW then they will bring it up for me! If thats the case, expect dynos by mid-week next week.

woot, yay for dyno's

Get some similar pics of it installed on your car DDM, at least then we can see if it was Minicobra's bumper that is mis-aligned, or if the production exhausts need a slight tweak to get the tips even. I personally like the way the passenger side tip is flush with the opening. :tup:

I don't have a lift so not sure I can get that same angle, but I will do my best to show how the tips sit.

I'm starting to slip to the darkside (FI exhaust). Berk, we need vids & dynos!

Haha, yeah, I was going to wait but I'm not sure right now.

he's working on getting the exhaust to DDM for dyno's, and I know DDM has a good camera. Only so much you can do when your in Cali and the car you are doing this for is in Vegas, lol

There might be a few SoCal 370Z owners who want to help.

Minicobra already game to get the final test fitment done. DDM is supposed to get it this weekend, dyno runs on monday. It can't hurt to wait until monday to order FI or Berk...FI is already booked through this whole month anyway. :)

They said they had videos, I'm just eager to see them.

not a fan of the stacked muffler design but the craftsmanship definitely looks superb! Good job Berk!

I'm excited to say we have just become Authorized Dealers of Berk Technology! The quality of their products is right in line with our goals...quality products built for the track!

Can't wait to see the results of the exhaust on DDM's 370z! Looking forward to its release!

Scott

This is a good plus having Nissan Dealer install it for you. Do you know how much you will charge with the installation?

Give me a call or shoot me a pm...I can work something out for ya!

Hey guys, yep that's my car :tup: Those are 20mm spacers on the rear and 15mm on the front. I have the Eibach springs installed with the SPC adjustable camber arms. I'm not sure what the camber is at the moment, I'll have to look that up, but they did return it more back to stock. After the Eibachs were installed there was noticeable neg camber, prob not bad, but I just wanted to get some better tire wear. With the adjustable arms I can always ad more neg camber for the track. :tup:

I didn't get to see the exhaust installed on the car, but i was able to see it, and I can tell you that the work they put into this system is amazing, the quality and the craftsmanship of the welds and braces are awesome. :tup:

Nice pics Brian, now where is the video you took :tup:

Have you guys seen this Berk 370Z video? Sorry if its a repost:tiphat:

Yeah that video is on the first page I think... but thanks anyways

Ok, Berk Tehnology came up to Vegas yesterday and brought exhaust prototype #2 here for me to test! Exhaust prototype #1 was the one in the first video, true dual, made with mild steel just for fitment. Prototype #2 is full stainless and they have brought up both an X-Pipe and H-Pipe for me to test! Hopefully I can get in tomorrow to do a baseline dyno at a local shop, then I will proceed with the install and test both setups!

I'm sorry to be such a pest, but a weight measurement would be great as well.

That's great, can't wait to see and hear the results :tup:

Yes, weight comparison is in the plans as well.

Baseline dyno today at 2pm!

Berk exhaust w/H-Pipe dyno tomorrow afternoon.

Berk exhaust w/X-Pipe dyno TBA (depends on the dyno shops schedule, but hopefully tomorrow as well)

eagerly awaiting....

be nice to see berk do a cai kit as well...

No plans on an intake system at this time. However I will say that there is a 20% chance of Berk developing a true high performance header system for the HR motor later in 2009. That for another thread and another day though. On to the exhaust weight!

I just put the parts on our shipping scale and here's where we are.

33.2 lbs - rear muffler section
8.6 lbs/ea - B-pipes (there are two)
xx lbs - Y-pipe -The Y-pipes are out for testing at the moment, I expect them to come in around 15lbs. Will update shortly.

For a system that is a true dual (more tubing & more flange connections), with an actual tangential siamessed X-pipe, and flex sections we are taking a slight weight penalty over the factory system but the performance gains FAR outweigh the weight impact.

We could save a few pounds by going with hollow exhaust hangers and thinner flanges but we would rather forgo the 3lb weight savings and build you a more robust exhaust system that should outlast the car.

i'll be going with your hfc's and the x-pipe catback in the near future....just need to decide on a good solid cai system

Well, I did a baseline dyno on the car today, but I am not happy with it so I think I am going to re-try tomorrow. Basically for some reason either the car is detonating and creating crazy torque spikes, or it is something wrong with the dyno. The air fuel was also in the low 13s which is a little leaner than ideal, especially in the 110 degree Vegas heat. This is the same dyno and shop I have used for all of my past dyno pulls with this car and this same situation happened to me during my original dyno pull when the car was completely stock. Back then, I got gas from a different gas station per the suggestion of the shop, came back the next day, and got a good baseline. I have another appointment for 2:00pm tomorrow that was supposed to be when I dynoed the Berk Cat-back with H-Pipe, but I think I might re-try the baseline. As the intakes may have leaned out the air/fuel ratios a bit, I am going to put the stock ones back in temporarily just as a precautionary measure. I will also get a new tank of gas from a the same gas station I went to before I got a good reading last time this happened. Not sure if any of it will work but I don't think today's dyno is a good baseline for what we are trying to do. Sorry everyone. Hopefully this will only delay dyno numbers for the exhaust one more day.

Wtf..EPIC FAIL ! I honestly don't care about your baseline. I just want to hear the exhaust and see the final #..I know why the comparison is there but I just don't care anymore.

Well the final number will still probably be lower than most are expecting. It was 110 degrees here in Vegas today. Not good for making power. Thats the whole purpose of getting a new baseline in the same temp conditions so you can look at the gains between baseline and cat-back instead of the overall number. Since the last time I dynoed the car I have put larger and heavier rear wheels/tires, added JWT intakes, and the air temperature has literally more than doubled. All of those have a huge impact on dyno numbers so the one I did today was ~15whp lower than my last dyno when it air temps were in the low 50s and I was on the stock wheels/tires.

So you're gonna wait until it's 50 degrees again ? Even though you dyno'd lower today the gains will still be the same. I definitely would take the intakes off but the wheels shouldn't really matter much. Tomorrow you should just go ahead and dyno the BERK exhaust with stock intakes. Why don't you do both tomorrow ? If nothing else you should use the rest of the day to install the exhausts and make videos of the sound of the exhaust ! I wanna hear the damn BERK exhausts and make a decision as well as a lot of other people I'm sure. If nothing else it's something to hold us over until we get the rest of the test results that apparently is going to be spread out over this week which isn't a REAL dyno comparison because it lets more variables happen when you don't do the dynos back to back. right ?

No no no, I am not going to wait until its cooler at all. I want to get a good baseline dyno in this heat though with the stock exhaust so we can get actual gains instead of the one I have which shows torque spikes over 500whp which obviously isn't right. Unfortunately I don't have my own dyno so I am at the mercy of the shop I go to's schedule, but the dynos most likely wont be more than a day apart. I personally think its better not to do it back to back anyway, although some would argue against me. I think the ECU on this car needs a little bit of driving around to learn the new mods. Plus the weather here in Vegas is consistent. Dry and anywhere between 108 and 111 degrees all this week.

I know people are anxious to hear it, but I am not going to install and un-install it just to get a quick video put up a day earlier than I am going to anyway. Sorry if that pisses anyone off.

Killin me smallz..

Mike,
I think Bryan might have a clip of the exhaust with x-pipe, at Idle and revving, maybe you can get him to post it up before things get ugly, LOL :bowrofl: IMO a lot of people on here (not all) are more interested in the sound/tone of the exhaust. On a daily driver, a good part of the driving enjoyment is the tone of the exhaust and engine. Most aftermarket exhaust are going to be pretty close in added hp numbers, somewhere in the neighborhood of 5-10hp. Me personally, I would sacrifice 5hp less for a better sounding exhaust. Of course if it was like 20hp difference, then maybe I would re-consider. but I don't think that will be the case. If there were 3 exhaust systems with only a 5hp difference in power, I would think people would tend to go with the one that sounds most pleasing to them.

+1 for Minicobra

+2 :driving:

IINCREASED weight kinda sucks but yes I would say power and tonal quality are still most peoples priority.:tup:

+3 Which is why I bought an exhaust for my 370z without any dyno numbers, y'all will see pics and video and dyno info as soon as I get it in... Think japanese jewelry!

Nick

Agree with the above statements but I would have to think that most would rather wait one more day for dyno numbers AND sound clips vs. just sound clips.
