Borla CrateMuffler SBC 283/327/350 2.25in Offset/Center 14in x 4.35in x 9in S-Type Muffler

This is the Borla 400849 CrateMuffler, specifically designed for Small Block Chevrolet 283, 327, and 350 V8 crate engines. It's built to optimize both the sound and power output of these popular V8s, offering a tuned experience that's often missing with generic mufflers. The S-Type designation means it's tuned for a more aggressive, sporty sound profile.

What sets this muffler apart is its directional flow design, which helps reduce or even eliminate annoying exhaust drone, especially on specific engine applications. You can identify the outlet by the mounting bracket welded to the endcap. It's constructed from well-built T-304 stainless steel, which is a stronger material than T-409 series stainless steel, offering better resistance to corrosion and ensuring long-lasting performance. The muffler measures 14 inches long, 4.35 inches high, and 9 inches wide, with 2.25-inch inlet and outlet pipes that can be either center or offset depending on your setup.

If you're looking for a more refined exhaust note or want to add a resonator for a milder Touring sound level, Borla offers part number 400937. This muffler is a solid option for anyone building a custom V8 or using a common crate engine and wanting a sound that matches the engine's character.
