i want my car to run faster than what it runs now. i an trying not to spend it on a turbo or supercharger. i want to know what the best exhast system is for my car. and i was wondering if i put 18' rims on my car will i mess with the computer system at all.because i have seen it mess with other cars.

 

uuuh.... use the search button dude.. exhaust is by preference mostly... I/H/E combo with cams will make you go faster then stock... if you get 18's itll throw off your speedometer so youll have to take it to the dealership to get it reconfigured. no it wont mess up the computer... use the search button and research. youll be able to find everything you need to know by using that

Read that.

You can get 18" for this car without any issues.
