That's a really awesome reply but it doesn't answer the original question.
And I'd suggest the VW emissions cheating scandal wasn't really madness at all. The US has fairly tough emissions standard, either you pass or fail but to actively fit electronics to cheat the system is a big deal. Yes those diesels are probably a lot better than what we had 10 years ago but that doesn't change the fact they didn't meet the new standards.
I'm sure we must have some of those cars here in NZ but as our emissions laws are still in the last century the government doesn't really give a rats ass.
So, back to the original question, do you modify your car in any way?
Like gossie said with new cars, but do I, well yes I have but not from 1999 new cars that I owned with the exhaust or engine, I had to remove the speed limiter in the VY SS as to the computer but that was it.
I chipped my 1995 VS V6 and did the exhaust and air box but was it worth it, no it was not worth the dollars truly. sure I lowered it and tried a lot of springs heights testing and better shocks working with camber settings and rear proportioning valve to get it just right and better brake pads.
My 1993 XG ute all it needed was better brake pads, the original were crap, at 210KM/H and hit the brakes you got bad fade from 70KM/H.
My 1999 VS V8 I just lowered it with better shocks and camber settings.
The VW met and exceeded the emission standards of the laws just gone past before it and it was as clean as, the points of contention were just BS in reality and if people are going to piss and moan about that crap you better be careful with a car that 1 year old or more because she may not comply you know as she did from new. the new laws are over the top to try to comply with and there is good reason why VW did what it did because they know better than the law in reality and the law should listen to the most advanced car maker in the world, who understands what's truly going on in reality, the law is not as advanced as VW is on the reality's, the law may be out of it's depths in reality.
The point I am making was with the law on pollution and noise comes under that as well and if you open up the exhaust, bingo she may not pass the law due to noise or emissions, because if you make the exhaust flow better the tune is now all out of wack, from what I have seen all such cars loose power when you do that, until it's tuned to it and only then you pick up more power.
I don't think that NZ needs EGR or cat converters, their is no health related point to the city's at all. the whole point is the health concerns of the people and that's where it starts and finishes, their is no less exhaust gasses coming out the exhaust pipe you know, more burnt and less not burnt in truth.
So to be simple, take a HX Holden with ADR27A vs the HJ, now the 173 got kicked out because it did not comply and the 202 could only be had in the HX ADR27A but in the LX Torana the 173 past the ADR27A, a lighter car bro could pass the so called test procedure but the bigger one did not, now as to the peramerters of the law that they use it's only with in the test procedure, they do not test flat out driving or beyond a point, it's just mainly about normal driving about stuff, like we have a loop mode with EFI and once you put your foot down to much she drops out of that loop mode that's another game again.
So who is to say that the law knows best in all fields, how would they truly know better than VW. is it polluting more truly ? or is it all just about keeping stupid moron so called greenies happy, we see the greenies do more harm than good pissing on about what they know f all about.
