Product Description

The Borla 400832 CrateMuffler® is a high-performance muffler engineered for **Small Block Ford (SBF) 289/302 crate engines and custom exhaust systems**. With a **2.5" offset inlet and 2.5" center outlet**, this muffler is built to fit a wide range of fabrication applications where a bold, aggressive exhaust tone is desired. Its **ATAK® internal design** produces a powerful exhaust note while maintaining strong flow characteristics, making it ideal for muscle cars, street/strip builds, and custom performance engines.

Constructed from premium T-304 stainless steel and precision CNC-manufactured, the 400832 balances durability and performance. The internal ATAK® design delivers a deep, aggressive tone with minimal drone for high-RPM engines, and the directional build (indicated by the welded bracket) ensures proper installation orientation. This part is intended for use in custom exhaust systems or with crate engines where standard vehicle-specific mufflers do not apply. It is backed by Borla's Million-Mile Warranty on construction quality, giving you confidence in long-term performance.
