Hi Mate,

I've the same exhaust on my R, and it's a very quite exhaust. It will easily come in under 90db, but if you plan on going for more than 320rwkw, this aren't the exhaust for you (i found this out the hard way).

Auto's do tend to be a little louder driving around.

However it is 3", has two mufflers that are of moderate size... it shouldn't be too far off legal, but not terribly loud at the same time. I suspect it would still be over 90dB however (if you are Vic)

Just keep your stock exhaust and swap over should you be pinned.

The EPA laws are so flawed in their design, application and archaic in nature that it's just easier to keep the stocker and swap back.

If you get 3 EPA's for exhaust noise you will be hauled in for a full test. Also if Police/EPA stations take photo's of the aftermarket exhaust, and you rockup with a stock one, things might become difficult after a while.

But look, you should be right. I've had more EPA's than i've had speeding fines and defects put together... and im still going strong because @ the end of the day, the Police can report you to the EPA without proof or even hearing the car, so if it ever goes to court over a suspension it will fall over.

Hi Mate,

Did you actually have to go through a test to confirm?

90dB @ 5100rpm is VERY quiet, so quiet the factory exhaust barely passes :)

But ye basic rule

3" = upto 300rwkw.

3.5" = 300-400rwkw

4" = 400rwkw+

You might have a point there, i was more going by feel. My old gtst went through the test, and it came upto 91db, whereas this seems a lot quieter. Than again the revs they test the gts and gtr are different.

Another point to keep in mind is, the older the exhaust gets, the louder it starts to sound(not by much, but it does generally get louder)

      Leak from Tokico BM50 Brake Master Cylinder

      By brillo · Posted

      Hi, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.

      R33 GTST Steering Rack (49001-19U05) Rebuild?

      By Gantai · Posted

      Well the install is officially done. Filled with fluid and bled it today, but didn't get a chance to take it on a test drive. I'll throw some final pics of the lines and whatnot but you can definitely install a DMAX rack in an R33 with pretty minor mods. I think the only other thing I had to do that isn't documented here is grind a bit of the larger banjo fitting to get it to clear since the banjos are grouped much tighter on the DMAX rack. Also the dust boots from a R33 do not fit either fyi, so if you end up doing this install for whatever reason you'll need to grab those too. One caveat with buying the S15 dust boots however is that the clamps are too small to fit on the R33 inner tie rod since they're much thicker so keep the old clamps around. The boots also twist a bit when adjusting toe but it's not a big deal. No issues or leaks so far, steering feels good and it looks like there's a bit more lock now than I had before. Getting an alignment on Saturday so I'll see how it feels then but seems like it'll be good to go

      Leak from Tokico BM50 Brake Master Cylinder

      By SteveL · Posted

      I don't get in here much anymore but I can help you with this.   The hole is a vent (air relief) for the brake proportioning valve, which is built into the master cylinder.    The bad news is that if brake fluid is leaking from that hole then it's getting past the proportioning valve seals.   The really bad news is that no spare parts are available for the proportioning valve either from Nissan or after market.     It's a bit of a PITA getting the proportioning valve out of the master cylinder body anyway but, fortunately, leaks from that area are rare in my experience. BTW, if those are copper (as such) brake lines you should get rid of them.    Bundy (steel) tube is a far better choice (and legal  in Australia - if that's where you are).
