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.

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.
