Usually considered to be simple devices that reduce the sound produced by engines, mufflers are actually masterpieces of engineering, and both their design and construction involve many advanced physical notions, including fluid dynamics and acoustics. Noise reduction, in fact, is the result of a refined design that makes the sound waves produced by exhaust flow eliminate each other through a system of tubes, channels and holes where the waves are reflected. OE mufflers are designed to ensure effective noise reduction to keep sound emission in a set range, according to the road regulation, yet taking scarcely into account the back pressure at the exhaust manifold outlet, a phenomenon that can consistently reduce performance. Performance mufflers are designed to overcome this aspect.

The smart and non-restrictive design allows performance mufflers to reduce the back pressure, while the refined tuning of channels, holes and tubes within the resonator chamber improves noise removal. In some design, a selected note can even be highlighted, to make the sound of your Nissan Altima's engine unmistakable and unique. In our online store, we offer a large selection of Nissan Altima performance mufflers built to rocket the efficiency of the exhaust system of your classy midsize car, yet conforming to current road regulations.
