WTB: Stock GSR Exhaust

[shields_05]

So I've been pulled over by the friendly NSW Highway Patrol and subsequently reamed with a referral to the Department of Environment and Climate Change. As such, I'm hoping someone here will have a full stock GSR exhaust I could buy to pass the DECC inspection. Preferably located around Sydney. Any help would be much appreciated, thanks.

Hmmm i feel ur pain brotha. Atleast thats all you ve gotta change, mine is whole motor basically or tune and im240. If the motor is pretty much stock, throw a decent cat in, and go for an im240 emissions test. They re free but have to book em. And then u will have a current emission certificate wit that exhaust on. That way next time the po po will have nothing.

From previously getting done by the DECC,

I can suggest the following

1) Get a good high-flow cat will need to be flange plated on both sides of the cat so it can be removed on the DECC checklist so they can tick that part as being removable if needed.
2) 2 Resonators in the middle since GSR is AWD you should easily beable to fit two. IM240 Emissions test is a must cause they it proves u can run high-flows and resonators within spec.
3) Get a Decent 2.5" or even 2 1/4" exhaust with baffle.

Standard GSR exhausts wont pass the noise test that is needed with it as due to the calibration of their machines when testing.. You may get a below 90db reading on 2/4" redline but they will get you on backoff. They will run 3 consecutive runs and if u get say 2 x 90db and 1 x 91 u will still pass.

All I can say is good luck Passing the noise is the hardest part...
