i would think that you would have a lot of trouble getting that through rego . I have heard that they wont pass fake side pipes if they can determine that there is a way you could hook them up after rego . The only way i have found to get around the problem is to make you system as if you were running side pipes but instead of having a tip at the end of the side mufflers have a flange there and run a basic 1 1/2 inch mild steel in and under the car joining in the middle and exiting out the back and if required to get the car under 90db put in a normal muffler under the car . Make it look like its meant to be there then after rego un bolt that section and bolt on a couple of tips to the back of the side pipes .

I am currently doing that now and should be done in about a month so i will post some pics when its done . My enginner was the one who told me this so it should be ok.
