Overview

It features chambers, baffles, or perforated tubes to dissipate sound waves while allowing exhaust flow. This muffler is a direct replacement for the original component on specific BMW models.

Show original supplier description

An exhaust muffler's primary role is to reduce engine noise by dissipating sound waves through internal chambers and baffles, while also safely directing exhaust gases out of the tailpipe. Its construction is intended to withstand the corrosive effects of road salt, moisture, and the elements, which can lead to rust and holes in the factory muffler over time. Symptoms of a failing muffler include loud or unusual exhaust noise, visible rust or holes, exhaust fumes entering the cabin, and reduced engine performance due to restricted exhaust flow. This genuine BMW part is designed for specific models, including the 335is and 335xi. It is compatible with various configurations of the E90, E92, and E93 chassis, all equipped with the N54 3.0L engine. The product is also noted as fitting vehicles with the "Factory BMW Performance Exhaust Upgrade." As a genuine BMW part, it guarantees a perfect fit and is manufactured to the same specifications as the original part installed at the factory. The "Genuine BMW" brand ensures you are receiving a part directly from BMW's approved manufacturing channels, maintaining the integrity of your vehicle's exhaust system.
