Dont forget that mnay of the titanium exhausts only run one muffler where others run two. So one less muffler also helps....and the few single muffler tiutamium exhausts i have heard sound great...but my god they are loud. With speed events typically havign to still be under a certain db reading....you could find yourself even getting kicked off race tracks. Duncan and SK need not worry as State rounds are typically no noice days...but us club guys? Expecially in Vic last year where i got several warning that saw me driving around off boost just gettign my eye in for a single session where i gave it hell :D

why don't they make exhausts with the V-band type flanges now? trust did make one before like that, and it's awesome. easy to fit/remove. seals well, no pesky leaks. I guess cost is the only downside, but it's not like you are going to have 10 bloody V-bands.

Maybe check here:

They are supposedly all good to the JASMA standards. Click the Nissan button & have a look at the pdf. My kanji is compelte rubbish so the columns may mean anything. :D

Yup... They're all 5.0 - 5.1kgs for the cat-back for the PE Ti-R and 6.7 - 7.1kgs for the PE Ti cat-back for GTRs.

Roy, What "speed events" are you talking about exactly?

Surely there wouldn't be any noise restrictions on private track hire days and private practice days? I just ordered a "bloody loud" Amuse Titan R1 exhaust which I fear will be very loud, and I don't want to run the car with a silencer :)

Brand and specs on this one? Titanium cat backs are very light, but not THAT light.... 5.x kgs seems to be the norm from what I've seen.

specs unsure of..bought of the forums..it does not have 2 mufflers its straight through into 4ich cannon.he said it was 3.1kg and well it felt light so i didnt even bother checking...2kg who gives a rats anyway...

sounds wicked thats alli cared about

deal Gary, what size do you want, and how long?

Andrew - yes there are noise limits at some tracks on some days. All NSW circuits have permanent noise meters but they often are not manned. The hillclimb tracks often have a noise meter, it depends on the neighbours (for instance MG Car Club at Ringwood and King Edward Park). They normally specify max noise at 30+ meters away from the track - when you think about v8 sports sedans and supercars being legal most skylines are OK with a big turbo in the middle of the exhaust quieting it down

I have a 900 mm Trust Ti cat back on the R32GTST and it is almost 20 kgs lighter than the 3.25" Nismo cat back that it replaced, which is now on the Stagea. I have been looking (albeit not very hard) for a source so that I can make the cat forward section out of Ti as well. So Duncan, you find some Ti and I'll get it welded.

Cheers

Gary

thats one big system....900mm....zero backpressure with that puppy!

deal Gary, what size do you want, and how long?

Is this an actress and bishop joke? :blink:

Obviously I would like 90 mm to match the back half. Length is tricky, 1m would be enough to do back to the joint where the wastegate pipe joins the turbine pipe. If I go any further than that (closer to the turbo) I would need 2 sizes, 75 mm and 50 mm. Plus it would need a lobster back welding job for the bends, which is very time consuming. To do the lot would require about 1 m of 90 mm, 1 m of 75 mm and 1 m of 50 mm to cover it.

Cheers

Gary

    • I'm back from the dyno - again! I went looking for someone who knew LS's and had a roller dyno, to see how it shaped up compared to everything else and confirm the powerband really is peaking where Mr Mamo says it should. TLDR: The dyno result I got this time definitely had the shape of how it feels on the road and finally 'makes sense'. Also we had a bit more time to play with timing on the dyno, it turns out the common practice in LS is to lower the timing around peak torque and restore it to max after. So given a car was on the dyno and mostly dialled in already, it was time for tweaking. Luis at APS is definitely knowledgable when it came to this and had overlays ready to go and was happy to share. If you map out your cylinder airmass you start seeing graphs that look a LOT like the engine's torque curve. The good thing also is if you map out your timing curve when you're avoiding knock... this curve very much looks like the inverse of the airmass curve. The result? Well it's another 10.7kw/14hp kw from where I drove it in at. Pretty much everywhere, too. As to how much this car actually makes in Hub Dyno numbers, American Dyno numbers, or Mainline dyno numbers, I say I don't know and it's gone up ~25kw since I started tinkering lol. It IS interesting how the shorter ratio gears I have aren't scaled right on this dyno - 6840RPM is 199KMH, not 175KMH. I have also seen other printouts here with cars with less mods at much higher "kmh" for their RPM due Commodores having 3.45's or longer (!) rear diff ratios maxing out 4th gear which is the 1:1 gear on the T56. Does this matter? No, not really. The real answer is go to the strip and see what it traps, but: I guess I should have gone last Sunday...
    • 310mm rotors will be avilable from Australia, Japan, and probably a few other places. Nothing for the front can be put on the back.
    • The filter only filters down to a specific size. Add to that, the filter is AFTER the pump. So it means everything starts breaking your pump even if its being filtered out.
    • Just like in being 14mm too small (296mm) makes it not fit, being 14mm too big (324mm) it also won't fit. You want to find the correct rotor.
    • @GTSBoy Ok so that was the shops problem...they showed R33 rotors on R34 page and i did not know 296 do not fit(and are for R33) Yes i bought "kit" with rotors and pads. Pads are ok(i have GTT calipers front and rear). They have some 324mm but no 310mm. So i dont know if they would fit. I have 17inch LMGT4s So another question. Can i fit those in the rear or they are just "too" big for that?
