mark_sudakov Posted July 7, 2008 Share Posted July 7, 2008 other more expensive option is to replace the catback system with either the Kakimoto Regu 06&R OR Trust Power Extreme II Link to comment https://www.sau.com.au/forums/topic/226973-db-exhaust-testing-and-nsw-regs/page/2/#findComment-3996470 Share on other sites More sharing options...
DECIM8 Posted July 7, 2008 Author Share Posted July 7, 2008 (edited) My exhaust is a N1 Mega Premium.. Basically the best one I think. The car has not been tuned correctly yet, do you feel this will help at all? Its been pre tuned but needs touch ups. Thanks for all the feedback, It was actually vibrating the windows on my friends n13 and I felt bad when parents were looking at me with their baby in the back seat.. otherwise I wouldnt be so fussy Edited July 7, 2008 by DECIM8 Link to comment https://www.sau.com.au/forums/topic/226973-db-exhaust-testing-and-nsw-regs/page/2/#findComment-3996651 Share on other sites More sharing options...

msnismo Posted July 7, 2008 Share Posted July 7, 2008 Yeah it's one of those things they often get wrong. You have to be insistent and make them read the law again.I've often wondered if you could just go to a dyno and do something like knock 20 degrees out of your timing, take the dyno printout to the tester and say, "look, peak power at 3500rpm and only 85kw too. db test is at 3/4 of that. " you may be onto something Adam!!! Wonder if its doable??? lol... Somehow I think they would tell us to get stuffed!!! Either or if its factory specs then I win hands down.... Im assuming the factory specs on a RB25DET are around 5,000 to 5,500 rpm seeing as most are tested at 3,800..... If it was tested on real power then umm imine should be tested at 6,150 ... Id epic fail for sure!!!! lol Perhaps DECIM8 can test your dyno sheet theory out!!

tbag Posted July 7, 2008 Share Posted July 7, 2008 so do the laws on exhaust noise outlined on the comlaw page apply to all cars or to cars from 1992 upwards?

DECIM8 Posted July 7, 2008 Author Share Posted July 7, 2008 Seems that way, Pre 1992 also have law restrictions for exhausts however they come down harder on us. so v8s etc get let off because they are classics.

tbag Posted July 7, 2008 Share Posted July 7, 2008 cause my gtr was built in 1989, the laws would be different for it then Link to comment https://www.sau.com.au/forums/topic/226973-db-exhaust-testing-and-nsw-regs/page/2/#findComment-3997988 Share on other sites More sharing options...

DECIM8 Posted November 5, 2008 Author Share Posted November 5, 2008 Just to bring back a old thread, Recived a letter today from DECC or the EPA because my exhaust is too loud. The public can supposedly submit a complaint for such a thing. Figured im going to a straight through muffler, for time being silencer is now in .. perm. Warning for you all .. watch out Link to comment https://www.sau.com.au/forums/topic/226973-db-exhaust-testing-and-nsw-regs/page/2/#findComment-4243428 Share on other sites More sharing options...
wisey18 Posted November 5, 2008 Share Posted November 5, 2008 Yep, that's true. I could turn around and say "Oh my next door neighbour has a loud exhaust" if I wanted to be a prick! Sounds like you've been stung dude. Bad luck.
