UDTRA 11in Long Muffler

The UDTRA 11in Long Muffler by SCHOENFELD is a specialized component for builders and enthusiasts focused on optimizing exhaust flow in high-performance vehicles. This 11-inch muffler is particularly effective in custom engine builds where traditional silencers may create backpressure and thermal inefficiencies. It is ideal for applications such as street rods, race cars, or modified small block engines.

Constructed from performance-grade materials, the UDTRA muffler features aggressive internal flow routing designed to minimize restriction. The extended length enhances expansion chamber volume, allowing exhaust gases to exit efficiently while managing sound levels through a strategic baffle design. This design approach helps to maintain performance without relying on restrictive packing.

This muffler is particularly beneficial for fabricators, engine builders, and DIY mechanics who are assembling custom exhaust systems from mandrel-bent tubing. It integrates well with headers, high-flow catalytic converters, and velocity stacks in both carbureted and fuel-injected applications, ensuring optimal performance in custom setups.
