i have a blitz neuro spec v silencer don't know if it will fit your car
quick two cents on this topic from past experience
girlfriend and i both bought r33 skylines
mine standard except for wheels already rego'd in act
passed rego first go at discount tyres, went to shop front 2 1/2yrs later no probs
Hers, exhaust wheels boost controller sequential bov, nsw rego
passed rego at shell servo first go but required vehicle identification check at dickson
off to dickson we go, i'd had one of these before takes about 5min, we go in 30min later still waiting
one of the supervisors comes in and question who inspected it said they never should have inspected it it is a highly midified vehicle the exhaust is to big, boost controllers are illegal, the bov is illegal but we will do a re-inspection free of charge.
fair enough than, thinking sh*t
failed on rear tyres borderline but chose to fail and rear seat not securely bolted (in prosess of doing stereo)
advised on all the rest (BOV ect.)
so then it got passed at dickson and also no more probs from RTA,
so yeah i guess it's luck of the draw
