Borla CrateMuffler Stock SBF 289/ 302/ FE BB 2.5 inch Offset/Offset 14in x 4.35in x 9in Oval Muffler

This is the Borla CrateMuffler, specifically designed to optimize the sound and performance of crate engines and custom builds, particularly for Small Block Ford (SBF) 289, 302, 351 Windsor, and FE Big Block V8 applications. Unlike generic mufflers, this unit is directional, with the outlet clearly marked by a welded mounting bracket. This design allows Borla to tune the sound specifically for these engine families, helping to reduce or eliminate annoying exhaust drone that can be common in custom setups.

Built from T-304 stainless steel, this muffler offers a well-built construction that stands up to the elements and provides long-lasting performance. The directional flow and specific tuning for SBF and FE engines mean you get a more refined exhaust note compared to a universal muffler. Borla backs this CrateMuffler with a Million-Mile Warranty, reflecting their confidence in its durability and performance.

If you're building a custom Ford V8 and want to control the exhaust sound and minimize drone, this Borla CrateMuffler is a solid option. For a Touring sound level, you can add their 400938 resonator.
