My exhaust is totaly diff to both of thoes i have what appears to be a single pipe leading into a "large box shaped device" (assuming this is the muffler as i have NFI) and then splits out of that to the 2 tips i think there is a cat on the single pipe to.

The single pipe and centre muffler are way behind the centre of the car. The parts we are talking about come off the exhaust manifolds then connect to a Y-pipe, which then goes into the single pipe. You HAVE to have 2 outlets from the engine, as the car is a V6 :)

Nice work man.. looks the Biz.

Where did you guys get your Megan Pipe from? I'm doing my research to see where is the cheapest to get it from considering shipping will probably be a killer!!

Any luck withe cats hitting the heat shield?

I am pretty sure I have this one - it is actually a Megan Racing copy

From memory the shipping was cheaper when I got it, so you might want to query the shipping rate.

Andrew at AM Performance ended up having to cut the passenger side Kinetix hfc in 2 places to get it to fit perfectly. Cost me $120 as it required removing the hfc and refitting a couple of times as well as the cuts and mig welding. Was spewing i didn't fork out the extra $200 or so for the titanium hfcs of another brand in the end. I emailed the US seller to tell him that the Kinetic hfcs do not fit properly and I am pissed off about it, but he didn't even take the time out to reply. Bolt-on my ass.

I also had a custom 3" mid-pipe made to replace the stock resonator piece and fitted a 3" Apexi ECV. But it turned out to be way too loud and raspy when full open. Then I did a country trip and somehow managed to tap the Apexi ecv on the driveshaft at decent rpm just hard enough to smash the ECV and ruin it. I subsequently pulled off the ECV and have now had Andrew fit a high flow resonator to the 3" mid pipe - it is now nearly silent at idle, but has a very healthy growl when I hit the loud pedal. Very happy with how it turned out.

Now I need to get some fat quad titanium rear pipes fitted to fill out the rear bar I have fitted - as the single pipe looks all lonely in the gaping hole around it on each side at the rear.

Wow.. you have had a Judas of a time haven't you!!

Still considering to get the Megan Y Pipe and now getting the Berk HCS's.. was going to get just the Y pipe and get a local exhaust shop to mock up some High Flow cats to suit however this may work out cheaper.. I was going to go 3" Hi flow but don't want to shift the power band too high seeing as I will run standard cams so will probably do this:

Standard Headers > 2.5" Berk HFC's> Megan Y Pipe (2.5inch inlet to 3 inch outlet)> Connect to my Fujitusbo Legalis (which I believe is 3" all the way.. will look up specs and measure my self).

I was considering the Fujitsubo Y Pipe but seems to be same specs as the Megan and the Megan is cheaper.

Just doing some quick research.. The Fujitsubo I have appears to be a 60.5mm (almost 2.5inch) to the resonator than 76.3mm (3inch to the muffler.)

My gripe is that the Megan Y Pipe is 2.5 converging to 3inches. This wouldn't be good as it will go 2.5inch to 3 to 2.5 to 3inch which will do wonders for flow!!

I have seen people online mating them up and not having a problem however don't want to restrict flow so may go around exhaust shops to see how much to cut the Fujitusbo resonator and put a 3inch inlet/outlet and possibly either making a Y Pipe or ordering the Megan and getting them to put it on.

I got a quote for around $850 for the Megan Y Pipe and Berk Delivered to Brisbane.

Thoughts? :action-smiley-069:

Hey NightCrawler,

Before you had a 3" mid pipe/resonator put in.. Was the mid pipe 2.5" inch to 3"?

Was there much of a difference?

Ideally larger would be better for top end though don't want to shift the powerband too high as I will have standard cams.

Spoke to Mick at Pipewerx. Awesome guy and have had him work on my previous cars and has always been straight up.

I was questioning him on whether it would be better to cut the current Fujitsubo Mid pipe and put a 3" OR leave it as it is and put the Megan Y pipe and his response was on the standard N/A specs.. Won't make a massive difference.

Obviously Top end would be better though not really redlining every shift lol.

He said I think it was the VY or VE SS that he said had 2.5" to 2.25" back to 2.5" which apperently on the Dyno gave the better mid range.

So am thinking of doing it and maybe changing it down the track.

Just don't want to effect flow by restricting though haven't heard any complaints byt the G35 boys.

May get him to fit (cbf as don't have a hoist) it (he didn't mind.. Could of said otherwise about the mid pipe).

I noticed the Fujitsubo Y pipe was the same so prob done to keep some mid range power.

To be honest I didn't notice any benefit in fitting the mid-pipe, but I did many things at the same time (which gave an overall benefit). Keep in mind too that the pipe from the axle-back section into my rear muffler is definitely 2.5", so that is the restrictive part.

But I am more than happy with it, and made 175rwkw on a VERY conservative Mainline dyno. And my V35 is an auto. And it is untuned as yet.

So the answer is, just keep your setup with the 2.5" in place - you really don't need 3" on a non-turbo car imho.

FYI when I finally got round to wiring up my SAFCII and getting Martin Donnon from Willall Racing to tune it, I got 183rwkw - not bad from an auto!

Well done old bean...

I installed BERK HFC's and love the response. The rasp takes a while to get used to. Even with the Fujitsubo it is there. Thinking of adding a resonator in between somewhere. Good Stuff though man. :-)

Yes mate, the passenger side one touched the heat shielding on the bottom of the car - had to pay $120 to get AM Performance to fix it.

Also of note is that when I pulled off the HFCs a couple of months ago to do some exhaust work (flexi joint on the cheap y-pipe broke and had to be replaced) the guts was gone out of one of the cats - so was just a shell in around 40,000km. Not great quality, as it turns out.

thanks mate, looks like I won't be getting the kinetix then...

How much for Nissan front grill? I'm wanting to do a full conversion from my US model(Infiniti) to the skyline Japan model(Nissan).

Some one might want to do a full swap with you. Maybe start a new tread

      Duncan's V37.......race car?

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      Duncan's V37.......race car?

      By Duncan · Posted

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
