The BMW Genuine Parts rear muffler (part number 18107505644) is a direct replacement for the BMW Z3 model. As a Genuine BMW part, it is manufactured to meet the stringent standards set by BMW, ensuring the same quality as the original equipment used in your vehicle's construction. This component is crucial for reducing engine noise and safely directing exhaust gases through the tailpipe.

When such damage occurs, necessitating replacement, this Genuine BMW part offers a direct fit and reliable performance. This rear muffler is compatible with various 2001 and 2002 BMW Z3 models, including the Coupe and Convertible variants with 2.5L and 3.0L M54 engines.
