This muffler fits most cars with 2.0""/2.5"/3" inlet (usually for non-turbo engines and exhaust with 2.5"/3" inlet). Getting more air into your engine and more exhaust out is the key to a performance motor. That"s where exhaust muffler is significant as the tip of an exhaust system. Larger exhaust tip means higher air flow efficiency, which prevent the backpressure that occurs in a common exhaust system. When cylinders don"t have to fight with each other to expel their exhaust, they can put more power through the wheels with the very minimum restrictions and your engine will perform at its potential. This muffler will increase about 8%-10% horsepower and will produce a smooth deep throaty tone. Sound level varies, depending on piping diameter and type of resonator.
