i had a 4age with extractors 2,1/4" pipe + resonator and muffler and it was right on the limit when it got tested for engineering. you could take a risk and go for the test anyway and could still pass even though its loud; as long as you are just under the limit they can't do anything.

i think mine was about 92db and was passed because its an old car. your ae92 might just be old enough too.

fair enough. i find the outside temperture seems to alter the loudness of mine from day to day. maybe if i pick a good day i'll i'll get away with it...?

I had the same thing happen to me, notice in the mail. I cheated my way out by putting someting restrictive between two of the exhuast flanges.

Grab one of those cheap chrome tips with a 30 deg downturn on it.

It will hide the steel wool you'll be shoving up there (temporarily)

 

Droop tips actually make your exhaust louder.

don't the epa dudes usually check to see if there are foreign objects in your exhaust? BUT on the upside if you put foerign objects up there you'll be +5kw :sob:

Carefull when you get your car tested, the tyre place that tests in ballarat doesn't test the cars right. My car was just on legal (after being tested incorrect) and they made me goto exhaust brothers to make the car quieter.

 

It wasn't randle who epa'd you was it? Exhaust shops can put in a flange with a restrictive gasket inbetween to make the car quieter too.

If you have a flange join somewhere, make a plate with about 5-6 holes at approx. 8mm in dia. in it. That worked on a mates skyline. It will give a little bit more back pressure but its only for the epa test.

Here's a bad effort for a diagram but I think you'll get the idea
