I have a 1999 JDM Toyota Altezza RS200-Z editioin. I imported the car directly from Japan and it had already been fitted with an aftermarket performance exhaust system. I like the performance on the car right now, and I was wondering how beneficial is it to "Upgrade" a stock car with aftermarket parts. How much, in aftermarket parts, can you put into a car until the car becomes "Unhealthy"? I'm asking this because this car is intended as a daily driver, and I have a friend that has don't everything you can possibley do to a car, but it's soley intended for competition. His car is in the shop most of the year...I don't want to get to that point. Thanks in advance.
