EPA - Need Std R33 GTR Exhaust - Please Help.


Recommended Posts

I just got EPA letter within a month after purchasing my car PLUS a defective notice for being too low, and the previous owner already get rid of the standard exhaust, therefore I need to ask for help from other R33 GTR owners....

Can I please borrow your exhaust for maybe 2 or 3 days? Any help would be appreciated, and does anyone knows any EPA tester without tighta$$ attitude?

And does anyone knows how they will perform the test? I mean I know that they will put the mic around 1 m away from the muffler in 45 degree angle, but what's the rpm point when the sound is measured?

Please do help me with the exhaust. :D

Any help, please email to [email protected] or [email protected] or sms to 0403413768.

En_One, i have a GTS-t full stock system, i don't know if the cat back seciton will bolt on... i have a feeling it MAY, as i don't think nissan would reshape the sheet metal under the car between the two models. Just check with a performance shop (give gerald a call at Ice Performance 0414359888) and see. If it fits you're welcome to borrow it.

Also Daalder in Box Hill tests them and they're reasonable fellas. Talk to matt.

Well being an expert on EPA testing, they have a little triangle type stand that is made of metal tube and they rest the microphone on a little holder that is attatched to the stand 1m away. The tip of this structure is placed at your exhaust tip and the test is carried out.

Attached to the microphone is a cord whic plugs into a hand held device that reads the db level of your exhaust. The tester sits in your car and revs it to 3300rpm. When the car has reached 3300rpm the tester takes his foot off the pedal and presses a button on the hand held device to record your noise output. This test is applied three times and either averaged out, or takes your lowest db read out. Cant remember.

The inspector then looks under the bonnet, and under your car and draws a very crude map of your exhaust from the turbo (or engine for all you N/A weaklings out there :D ) on your certificate. You then pay $27.50 and either pass or fail. the max db level you are allowed is 90db. I was once told by a very reputable GTR guy, that even a TOTALLY STOCK GTR exhaust system registers 89db.

You get given the yellow copy for your own records and send the green copy (with your EPA letter) to the EPA.

If you get tested with a resinator, you have to keep that resinator on at all times. If you get caught without it there are big fines and penalities. So NO you cant JUST put a resinator on. Better to put on the stock exhaust (which is just to Farkn obvious) or do a Ross special :D

3500? A place in Footscray tested it until 4100 rpm and I got the reading of 90.5 decibel.... Which one is true? LOL if only 3500 I don't think my xhaust will be that loud. <--- sorry i mean 5100 and when I was asking them why it is 5100 they said because it is the rule for twin turbo!!!!!!!

Well when u have a full epa test u have to take your car to the epa test station in mcloud. U got charged $27 because u went to an exhaust shop and they gave u a certificate which they send to the epa.

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
