Borla CrateMuffler 2.25in Offset-In/Offset-Out in S-Typein Stock Sbf 289/302/351

This is the Borla S-Type CrateMuffler, designed specifically for Small Block Ford engines like the 289, 302, and 351 Windsor V8s, excluding the Coyote 5.0L. It's built to optimize sound and power for crate engines and custom builds, offering a unique solution for enthusiasts looking to fine-tune their exhaust note.

What sets this muffler apart is its directional design, meaning it's tuned for specific engine families to provide a custom sound and significantly reduce or eliminate exhaust drone. The outlet end is easily identifiable by the mounting bracket welded to the endcap. Constructed from well-built T-304 stainless steel, it offers better corrosion resistance and durability compared to T-400 series materials. This muffler is designed for an accurate fit thanks to precision CNC manufacturing.

For those seeking a specific sound level, adding the Borla resonator (part #400937) can help achieve the Touring sound level. Borla backs this CrateMuffler with a Million-Mile Warranty, reflecting their extensive experience in exhaust systems.
