About this part

Product Details

Borla is known for its extensive experience and success in exhaust systems. This CrateMuffler is built specifically for custom-built motors, like the Big Block Chrysler, Dodge, and Plymouth V8s (383, 413, 426, 440) that you might be using in a project car or hot rod. It's designed to optimize both sound and power for these specific engine families.

This muffler has a directional flow, which you can identify by the mounting bracket welded to the endcap – make sure to install it with the bracket facing the outlet. This directional design helps tune the exhaust note and can significantly reduce or eliminate annoying drone, especially on these larger displacement engines. It's constructed from well-built T-304 stainless steel, which is a strong material that resists corrosion and ensures long-lasting performance. For a slightly different sound level, you can add their 400938 resonator to achieve a Touring sound.

Borla backs this muffler with a Million-Mile Warranty, reflecting their confidence in the product's durability and performance for your custom build.
