Product Details
Borla is known for making some of the most experienced and winning exhaust systems out there. This CrateMuffler is built specifically to get the best sound and power out of crate engines and custom builds, like your Small Block Ford 289, 302, or 351 Windsor. It's designed to be directional, meaning it's tuned for a specific engine family to give you a custom sound and help cut down on that annoying drone you sometimes get on the highway.
This muffler is constructed from T-304 stainless steel, which is a strong material that holds up well over time and resists corrosion better than some other stainless grades. The directional design is pretty neat; you can tell which way it goes because there's a mounting bracket welded onto the end cap. If you're looking for a more mellow tone, you can add their 400938 resonator to this setup. Borla stands behind their work with a Million-Mile Warranty, so you know it's built to last.
