Hi all,

Just wanna know if any V8 owners have had to have the above test done.
My system only has the rear mufflers removed, so I wouldn't think it would fail, but I have no idea..
Some overly keen police officer seems to think so..

Anyway, just after peoples results, and the set-up they were running at the time.

Cheers, Sean.

Unless your replacement pipes and tips add to the noise, I would be very surprised if there was a problem.

After removing the centre resonator and two mid mufflers, and replacing the rears with Hi-Flo's, my own testing with a borrowed sound meter is borderline legal, possibly slightly over.

Thanks Pen,

I had it tested yesterday and registered 103db.
It was the back-off that tipped the scale.

Re-fitted the stock rears and registered 83db.

I've gotta say, it did surprise me that it was over.

I don't think mine would pass. And my car isn't exactly noisy compared to some.

Yeah same James. Makes me wonder if any cat-back system would be under 90db, given my exhaust is now completely stock, and dead quiet, and so close to the limit.

At least I can't be tested for another 6 months..
