Looking for options for a Cat Back system to suit R34 - 4 Door - N/A.

Had a Fujitsubo Legalis R system ( 70mm diameter main with the twin 90mm tips ) on order through JDM Imports ( Trader ) since Nov last year but don't expect I'll ever see it ( or my $600 deposit ) so I'm now looking for other options.

So what do you have ? How much ? How loud ? Where from ?

Cheers.

P.S. Not interested in any loud / droney systems.

Would anyone know if a cat back from a R34 GT-R would fit a R34 sedan ?

Might be difficult.. Pkus a GTR cat-back it's too big for a N/A i would think... You need something smaller like 2.25 or 2.5.. There aren't many premade systems out there that offer a 2.25 or 2.5 system, you will usually have to get something custom made from an exhaust shop.. This isn't that expensive either.

I got a 2.25 cat back system from hi-tech exhausts in syd, sounds nice and doesn't drone.

Yeah, was considering a 3" Fujitsubo Legalis R for a turbo. Since they are mega quiet on a turbo I was thinking it might sound good on an N/A. :P So, what about the fitment ?

Hmmm. Was giving Hi-Tech some thought. What sort of $'s for a cat back from Hi-Tech ?

yea once again stay away from 3' cat backs..

Catback from hi-tech.. anywhere from $450-$700, how sharp are your bargaining skills? ;)

Cheers for that Nick. I don't mind Hi Tech but I prefer an "off the shelf" option if I can get it.

Has anyone got anything other than a Hi Tech or Fujitsubo to suit this set-up ?

I do NOT recommend Hi Tech Mufflers.. the guy who did it was rude, loud, unhelpful and generally talk to me like i'm a 7 year old and am really stupid..

this is the thread of the story

http://www.skylinesaustralia.com/forums/in...142090&st=0

Recently I had to adjust my exhaust beacuse it was rattling against something under the car, and I did not go to high tech to get it fixed, I rather pay another exhaust shop to do it.

Up to this day, I haven't checked whether the other resonator is stainless steel, I was thinking if it's not.. I'll use it for a year then get it changed..

cheers

Oh man, I totally forgot about this episode with you & Hi Tech !!

I think I'm just going to have to re-save the $'s and buy an off the shelf system.

Cheers for the reminder :(

are you looking for a budget upgrade for power? or something that sounds good?

i'm about to throw a standard GTR exhaust onto my NA, it's 2.5" and lines up exactly. giggidy

Looking for something that flows better so the revs above 4K actually have a reason to exist :D and of course, I need some sort of sound other than hissing ;)

Interesting thought though........ I wonder how much better ( if any ) a factory R34 GTT sedan zorst would be compared to what I have atm......... :)

you did the washer nozzles thing *bows*

it's my pleasure =)

seriously at this point of time I really regret not putting anther 400-500 bucks out and getting a jap system.. it'll def get rid of the drone..

cheers

not sure about the exhaust sizing in the r34s, but in the r32/r33's the turbo variants have a slightly larger exhaust.

i'd not expect them to extract every last kilowatt from your setup, but bang for buck wise - they'd be a cheap and reasonably more than enough upgrade. considering you can pick up a stock exhaust for next to nothing.

So, from now on I'll be known as "The Washer Nozzle Guy" ?!?! :D

Yeah I've decided to give away the whole idea of getting a system made up. Going to go back to looking at bolt-up systems. :mad: I've never had a really bad boltup system :(

That will be the fall-back plan then ! Got a few other options to try first. Cheers.

If anyone's interested, here's the one I'm getting........

Our friends at Nengun have been kind enough to recently put this item on their list of exhaust systems available for purchase but I have already got the ball rolling with our other good friends at JustJap who are getting it for me :D

And just for the sake of sharing info, for those looking for a Cat-Back system, here's the range from Kakimoto.

Enjoy ! :laugh:

I've been looking for an exhaust for a V35 Coupe, and came across the HKS Hi Power Ti. Absouletly awesome sound. I suspect it will be quite different on an RB compared to a VQ, but if the same basic sound is there go for it. It's got this awesome high pitched growl that you'd expect from a supercar.

Jump on You Tube and type in G35 Coupe HKS Exhaust, you'll get a few recording of yanks jumping on the loud pedal.

Haven't checked but I think I heard HKS may have sound files on their website.

yo mate. so you getting the Fujit or the Kaki exhaust? =)

oh when u r done.. mind if i drop by to listen to your exhaust? hehe

may i ask how much this cost you? as i am also in the market for one

Getting the Fujitsubo Legalis R stainless cat-back one with the 70mm main pipe and twin 90mm tips so it looks nice and standard :pirate:

For sure, I'll let you know when I've got it and fitted it so you can have a listen ! I don't expect it's going to be anything noticeable since Fujitsubo are without a doubt, the quietest systems available.

Here's the dB stats on the Fuji system:

At idle: Stock 63 dB - Fuji 57 dB

3000rpm: Stock 75 dB - Fuji 79 dB

5000rpm: Stock 82 dB - Fuji 84 dB

Approach exhaust noise at 4500rpm: Stock 80dB - Fuji 84 dB

The Kakimoto ones are the ones to get if you want a growling exhaust note & a cannon tip. Kaki's sound MEGA tough on N/A's but I just want some top end flow, but I don't want attention :happy:

DVS R34, expect to pay around $1,000 + for any of these top shelf N/A systems. Worth every cent IMO !! :wub:

Now I just have to wait for 6 weeks :)

hmm... would be keen to see how it sounds.

for some reason twin cam NA's seem to be quite difficult to find a suitable not too loud, but not too quiet type exhaust.

6 weeks is a long wait... i'll be keen for a sound file or video.

    • Also, I logged some data from the ECU for each session (mostly oil pressures and various temps, but also speed, revs etc, can't believe I forgot accelerator position). The Ecutek data loads nicely to datazap, I got good data from sessions 2, 3 and 4: https://datazap.me/u/duncanhandleyhgeconsultingcomau/250813-wakefield-session-2?log=0&data=7 https://datazap.me/u/duncanhandleyhgeconsultingcomau/250813-wakefield-session-3?log=0&data=6 https://datazap.me/u/duncanhandleyhgeconsultingcomau/250813-wakefield-session-4?log=0&data=6 Each session is cut into 3 files but loaded together, you can change between them in the top left. As the test sessions are mostly about the car, not me, I basically start by checking the oil pressure (good, or at least consistent all day). These have an electrically controlled oil pump which targets 25psi(!) at low load and 50 at high. I'm running a much thicker oil than recommended by nissan (they said 0w20, I'm running 10w40) so its a little higher. The main thing is that it doesn't drop too far, eg in the long left hand fish hook, or under brakes so I know I'm not getting oil surge. Good start. Then Oil and Coolant temp, plus intercooler and intake temps, like this: Keeping in mind ambient was about 5o at session 2, I'd say the oil temp is good. The coolant temp as OK but a big worry for hot days (it was getting to 110 back in Feb when it was 35o) so I need to keep addressing that. The water to air intercooler is working totally backwards where we get 5o air in the intake, squish/warm it in the turbos (unknown temp) then run it through the intercoolers which are say 65o max in this case, then the result is 20o air into the engine......the day was too atypical to draw a conclusion on that I think, in the united states of freedom they do a lot of upsizing the intercooler and heat exchanger cores to get those temps down but they were OK this time. The other interesting (but not concerning) part for me was the turbo speed vs boost graph: I circled an example from the main straight. With the tune boost peaks at around 18psi but it deliberately drops to about 14psi at redline because the turbos are tiny - they choke at high revs and just create more heat than power if you run them hard all the way. But you can also see the turbo speed at the same time; it raises from about 180,000rpm to 210,000rpm which the boost falls....imagine the turbine speed if they held 18psi to redline. The wastegates are electrically controlled so there is a heap of logic about boost target, actual boost, delta etc etc but it all seems to work well
    • hahah when youtube subscribers are faster than my updates here. Yes some vid from the day is up, here:  Note that as with all track day videos it is boring watching after the bloopers at the start.  The off was a genuine surprise to me, I've literally done a thousand laps around the place and I've never had instability there; basically it rolled into oversteer, slipped, gripped and spat me out. On the way off I mowed down one of the instructor's cones and it sat there all day looking at me with accusing cone eyes as I drove past. 1:13:20 was my fastest lap, and it was in the second session, 3rd lap.  It (or me!) got slower throughout the day as it got hotter.      
    • It sounds like you want what the Toyota Landcruisers have for their roof racks. Wanna know what you end up with? Rust holes in the roof, and water everywhere...
    • Discovered today that if I select reverse first and take my foot off the brake, then select drive, the drive indicator light works and so does the tiptronic gear indicator. 
    • Ok so after much research and talking with knowledgeable people I've got my turbo conversion done and it's all running great other than 1 small issue.  Car has remained auto with the na auto and tcm, I've used a stagea ecu with. NIstune board and everything is great other than my gear selection on the dash. It illuminates park, reverse, neutral, 3rd and 2nd. But nothing drive or what gear your in when you pop it into tiptronic.  I'm sure there is maybe 1 wire in the ecu plug I need to move to rectify this. Does anyone here have any ideas?   Cheers guys
