To Mod your Mom's car to turn heads follow my three easy steps. While Mom is at the hairdressers:
1) Pimp the tailpipe with a Performance Exhaust: Have a muffler shop that knows what they're doing upgrade her exhaust system. The term for what you want is a "header-back" exhaust which will greatly increase the amount of noise the car makes and produce a deep, growling sound.
2) Take off her air silencer ( black tube in the fender connecting to the air box ) get more kick with a side of hearing her engine inhale.
3) Fit a Cold-Air/Ram-Air Intake: This is a simple upgrade that makes her air intake draw in air from a cooler place outside her car.
The odds are that your mom will not notice the difference, but your friends sure will !!
