Epa Fun

[R31Nismoid]

I just about passed with a FULL 3.5inch exhaust today (95db)

Minor alteration in a couple places and i'll get under the limit no problem in the world, know exactly what i need to do, and be legal doing it.

Goes to show, a properly engineered exhaust can still flow for 400rwkw, and pass noise testing without even having to worry

what exhaust do you have? what do you plan doing to modify for epa test?

[R31Nismoid]

I had a 100% custom made one

Put it this way, an exhaust made to PASS EPA isnt cheap, and im not talking $1500 here either.

I've paid some damn good money to have it made, and the results speak for themselves. Even the EPA guy doing the test was highly surprised at how close it was to legal for such a free flowing system (will flow 400rwkw no worries if it needed to do so).

Considering all the crappy Jap systems that he would see on a daily basis, my car was a very very big surprise with results it returned.

Some people have said that cost was too much, but IMO it far outweighs the costs of constant defects and EPA's... which over the years have cost me a fortune alone.

Minor alteration to mufflers and it will be fine, will pass without even thinking about it.

That was running a CAT and all the other bizzo aswell.

Crappy Jap systems? Settle down...i'm sure yours is very nice but calling the jap systems rubbish because they don't pass an AUSTRALIAN noise limit is a bit much....

[R31Nismoid]

Well them not passing isnt my problem is it?

The laws are here, you comply the car to AUS Import Regulations and other AUS laws. So why not the noise laws too?

Its not really a 'bit much', there is a fair bit of crap on the market.

Why pay $$$ for a Jap exhaust if it doesnt even come close to passing? I dont really see the point, and hence ive always had locally produced exhausts

....

how can you call a japanese exhaust system crap because it doesnt pass an australian noise limit...thats 1 of the stupidest things ive ever heard.

not to mention the fact that plenty of jap systems can pass the australian noise limit if thats what you want, without being modified and costing less than $1500.

havnt read the whole thred but i was recently was in the same situation. i just paid 100 bux to borrow a full stock r34 gtt exhaust.

i went to revzone

They might pass, but will they flow for the power is the question

Mate you could always just make up a small plate with about an inch opening or so depending on what you need, and just bolt that up between where the cat and catback bolt up, easy to take off after just make sure its not too obvious as in nsw they lift the car up and do a thorough check with pics, best way to hide these things is get some exhaust sealer from supercheap and cover the joints up...

that or invest in an Apexi EVC like i have, saves ALOT of hassles!

[R31Nismoid]

The above is illegal.

[Taleb Tyres]

Yep, hence the exhaust sealer over the joints to cover it up, if you were to follow that path...

yeah, what needs doing? will it still be full 3.5in?

mine is quiet but still a little loud (it's probably more or less exactly like yours, except for differences in the under body shape
