Hu?
Thats just plain stupid. Unless it was because of the diameter of the piping (and even then, its still debateable) there is no way the MATERIAL used is gunna change ur emissions... Unless PVC reacts with air and releases some kind of combustable gas... im quite certain he just defected u cause of the diy frankenstien cai. Lol... that just sounds funny read out loud....
You see, here in SA they find anything to defect you just to piss you off. When we get defected, the whole car has to be inspected, it doesn't matter if you were only done for too low or whatever, everything MUST be returned back to stock so you have a chance to pass the inspection.
1. you get defected.
2. you have anywhere from 1hour to 3 days (at the cops discretion) to drive your car.
3. you have to book an appointment for a roadworthy, our minimum wait time is at least 1 month, usually 6weeks. During this time, you're not allowed to drive your vehicle unless you're going to a place of repair OR have got an excemption from a police station when they beleive that the car is ready for a roadworthy inspection.
4. You spend countless hours fixing your car, or giving it to somebody to fix which is $$$.
5. After your 6 week wait, you go to regency (where our roadworthy place is), you pay your $80 and they inspect your car. What they usually do here is defect you for MORE things (worn bushes and other misc bullshit) and you go home on double defect, and have to wait another month for another inspection.
6. You go back after your wait, and you pay another $50. If you've done all the things on the form then they will pass you, if not, the cycle continues.
7. You get off defect, go home, put the bits you got defected for on again.
No such things as mod plates here either.
So as you can see, the cops are pricks to us because they know how much bullshit it is.
