Do I need them for a warrent, and if theyre taken out do it make the car louder!

Quite sure you don't need them for a warrant, and please don't take it out to make your car louder. Your chances of being cool and/or getting laid will not improve.

depends when vehicle first reg in NZ if needed for a WOF, no it wont make it any louder if removed

Brought a v8 so I want it to sound like a v8, thanks for your help.

Why didn't you just buy a V8 that sounds like a V8 to start with!

New requirement to fail vehicles first registered in NZ from 1 May 2010 that have a catalytic converter removed where one was originally fitted (need to fit a catalytic converter or pass an emissions test at a TSDA)

removal will increase the noise but check if you have got co sensors after them if so your engine management will activate if removed
