Do you want your sports car or truck to have that deep throaty growl when you take off at an intersection? Vroom, vroom, vroom! It’s easy enough to do by having an exhaust system installed that lets the exhaust from the engine flow more freely out the tailpipes. This type of upgrade will make your engine sound a lot more powerful and even improve gas mileage.
Two popular systems, which can be installed for less than $400, are Magnaflow and Flow Master. The muffler is changed and dual tailpipes with special tips are added. Some of the tips even have patterns on them. The louder exhaust systems do comply with California law, but be aware that you can be ticketed for driving around with a muffler, which you have modified yourself, that makes too much noise.
