Ok lah Artage,
don't joke with you. Since you got bodykit and GT wing already, and
you want that vroom-vroom sound, you can do it cheap without buying
turbo or supercharger whatever.
Is your car stock? Just go change your exhaust muffler. LTA got
approved many. Choose any brand you like that fits your car. Im not
sure which one, but with an aftermarket muffler, you car will sound
loud. The harder you "zua", the louder the vroom.
