Nismo Exhaust

[looking for a skyline]

does anyone has a NISMO "3 INCH FROM CAT BACK 5 INCH CARBON FIBRE TIP" Exhaust? the model number is 20100-RN591. i wanted to know whether it is EPA legal and it has any drone to it? my R33 is stock standard. planning to buy it second hand. i m after an exhaust which sounds a bit more than stock.

attaching a few pics as well.

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).

I have one of these, it is a bell mouthed tip so dont expect it to be quiet, I was EPAd with mine, but hey they look good!

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.

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+

I have a stock exhaust system for this reason, it only just passes EPA test. the windows rattle with the nizmo exhaust so im told.

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)

Great exhaust. Have one in my car and love both the look and tone if it. No tinny sound or vibrations. This things solid.
