I am thinking I will install the supercharger and get it running thru the 3", then add the smog piece, then depending on the timing, head down to the VASS guy shortly afterwards. I asked the VASS guy what he wanted to see and the smog device was all he mentioned. If he wants a drive by I will see if i can take it easy, but mine is pretty quiet now. I will have had enough of the car by then I reckon, so will probably park it up. Bit unsure where I will be with work as well, could well be interstate for the first 4 - 5 months of 2019, so just have to play it by ear. Parts dont arrive until the 3rd week of jan at this stage. Post that I will open it up to 4" after the smog device - unsure who will do this at the moment.
