Yeah you just got unlucky bud, you don't need mesh on the intercooler nor heat wrap on the piping. Chances are your exhaust isn't even too loud, reverse lights you will need to check though. Just make sure everything works, all your windows, windscreen washers/wipers, make sure there is water in your washer bottle, parkers, headlights, high beams, brake lights etc. Just common sense things you know.
