Custom Titanium Exhaust

[Roy]

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

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.

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.

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.

Spec R...no muffler?

No muffler? Hardcore

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

[gun32gtr]

duncan,

did they have noise limits at the hill climbs/supersprints in bathurst last event???and also what is the db limit

[Duncan]

don't think they do, but you need to check the supp regs at each event.

[rev210]

Inconel manifold would be nice.

[Duncan]

Troy did you mean these guys? http://www.specialtymetals.com.au/index_files/products.htm they are in WA. Don't list Ti tube but I'll give em a try

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!

Damn too many zeros

Should be 90 mm

sorry Gary, couldn't help myself.

I could do with a titanium system too but my body needs to lose 10kg more than my car does.

[Duncan]

hmm well I figured it would be easier to save weight with the zorst than the driver.....

[Sydneykid]

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

Is this an actress and bishop joke?

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

let us no if any of them are useful

[Angus Smart]

West side exhaust in padstow were making up some titanium exhausts before.

could be worth a shot calling them to find some.

tho it is possible they got scrap stuff from xforce and cut it up.
