Is car sunshade fineable by LTA?

Hi bros and sisters, need advice. Bought a car with supersprint exhaust fitted, has cert but not registered under LTA. Have friends driving the same car with the same exhaust fitted but theirs are registered and legalised but when I called LTA up, LTA told me is not legalised nor registered in the data for my car. Called Jeep Chee to clarify but they say the exhaust was never legal, but everyone I know driving the same car has the same exhaust fitted and is all registered etc. Any advice?
