Any car that has its original parts removed / cut / modified / adjusted will void warranty la. That includes open pod and DIY CAI la..
Joeker's car is one helluva chun car la.. got lohmaikai air intake, bbq super large exhaust (can fit my fist in!), bride seats, no back seats, 4 point belts, meters, turbo, CF hood.. I tells you.. his car is almost ALL DIY.. might as well call it the Proton Joeker. :lol:
