About this part

Product Details

This Borla CrateMuffler is designed specifically for Mopar Big Block engines like the 383, 413, 426, and 440 V8s. It's built to optimize the sound and power of crate motors or custom builds, offering a unique S-Type sound profile. The muffler is directional, meaning it's tuned for a specific engine family to help reduce or eliminate annoying drone, which is a common issue with performance exhaust systems.

Constructed from well-built T-304 stainless steel, this muffler offers better corrosion resistance and durability compared to T-400 series steel. The outlet is easily identified by the mounting bracket welded to the endcap, ensuring it's installed in the correct direction for optimal performance. Precision CNC manufacturing helps ensure an accurate fit, and Borla backs this muffler with a Million-Mile Warranty, reflecting their extensive experience in exhaust systems.
