WazR32GTSt Posted January 28, 2008 Share Posted January 28, 2008 if you have ANY part that isn't standard on your car, then technically you need a mod plate it might be legal (as in under 90dB) but you need an engineer to prove this most don't bother but if you got done then unfortunately they are within their rights Link to comment https://www.sau.com.au/forums/topic/203433-mod-plate-for-exhaust/#findComment-3607894 Share on other sites More sharing options...

Col-GTSX Posted January 28, 2008 Share Posted January 28, 2008 A simply rule of thumb for you; If the car comes standard with a item and you replace it with a "better" or "different" item you do not require a mod plate. For instance i put a high mount turbo on my r33 when i had it, and no i didnt need a modplate as he car was factory fitted with a turbo. I was simplly changing it for a "better" aftermarket item, and i still included all anti-polution items required to make it 100% legal... So in short no you do not need a mod plate for an exhaust at all. As for legality of the exhaust all you need to watch out for it that at the lowest point it is more than 100mm off the ground and that it is not over 90db and you'll be fine...

dangerous_daveo Posted January 28, 2008 Share Posted January 28, 2008 Well my understanding was depends on which law they are reading, and thier personal interperatation of that law. Either way the system needs sorting out so its the same for all states, with one interperatation.

That was my understanding, something like changing your exhaust falls under the "light modification" rules for queensland transport. Only the "heavy modification" like engine/transmission swaps, changes to safety features (e.g. cages) etc etc required mod plates. Unfortunately then there's the new police rules which don't seem to coincide and leave people wondering/fined etc. Link to comment https://www.sau.com.au/forums/topic/203433-mod-plate-for-exhaust/#findComment-3610055 Share on other sites More sharing options...

bloodzkull Posted January 29, 2008 Share Posted January 29, 2008 go to court. the actual fine should read "modifying a silencing device so as to reduce it's effectivnes" probably worth a try arguing that it's purpose is to keep the car below the set legal limit, and that it still does that so it is in fact not reducing it's effectivness. was it a traffic cop? better chance if it was as most magistrates don't really seem to like traffic cops.

Col-GTSX Posted January 29, 2008 Share Posted January 29, 2008 Another way to think of it; Ok, so a car has an OEM exhaust from new, you drive said car for 5-6 years and it starts to devolp an exhaust leak. So you take the car to an exhaust shop and simplly say fix it, so they then find there is a rust hole in the muffler and say no worries we will put a new muffler on. If one were to need a mod plate, technically this person above would require one too. As no exhaust shop puts in OEM parts even when simplly replacing a dodgey muffler. Hence requiring a mod plate for an exhaust is not true, as almost every car thats more than 10 years old would have had some form of exhaust mod made, and if a car were 15+ years old the entire exhaust would have probablly been replaced at some stage.
