Hi Bosses.

I am a newbie for this forum.
The story is like that

i just place the booking fee to a second hand car dealer for a CR-Z
Details:
Mileage: 16k
Manufacture date: 2012
register date: sept 2012

So the CR-Z exhaust pipe and the open port has been modified
beside that,
the power bank/ power charger also been installed.

Under these modified,
Does the car engine warranty and battery warranty still valid?
