Borla CrateMuffler Big Block Mopar 383/413/426/440 2.5in Offset/Center 14inx4.35inx9in Oval Muffler

This Borla CrateMuffler is designed specifically for Big Block Mopar engines like the 383, 413, 426, and 440 cubic inch V8s. It's built to optimize both the sound and power output of these larger displacement engines, whether they're crate motors or custom builds. You'll get the aggressive ATAK sound profile that Borla is known for, with a design that's tuned for this specific engine family to help reduce or eliminate drone.

The muffler is constructed from T-304 stainless steel, which is a well-built material that resists corrosion and offers excellent durability. This particular model has a 2.5-inch inlet that is offset and centered, and the muffler body measures 14 inches long by 4.35 inches wide by 9.10 inches high. It's directional, so pay attention to the outlet end, which is identifiable by the welded mounting bracket, to ensure proper installation and the intended sound tuning.

Borla backs this CrateMuffler with a Million-Mile Warranty, reflecting their experience in exhaust systems. While this muffler is designed for specific engine displacements, always check the manufacturer's fitment guide to confirm compatibility with your particular application.
