Borla 3in ID In/Out x 34in x 8.5 in x 5.5in Oval XR-1 Multi-core Racing Muffler

This is the Borla XR-1 Multi-core racing muffler, part number 400115. While designed with Pre-Runner trucks in mind, its universal nature means it can be adapted to many other applications where maximum exhaust flow and a specific sound profile are desired. The long body design, measuring 34 inches, is particularly well-suited for trucks and helps manage exhaust sound effectively. This muffler is built for high horsepower applications, featuring Borla's patented Multicore technology that actually outflows a straight pipe in testing, ensuring minimal restriction.

Constructed from T-304 stainless steel, this muffler is built to last and will not rust. The 100% welded construction adds significant strength, and the internal packing uses high-temperature T-304 stainless steel wool for effective sound control that resists burnout. Its reversible design offers flexibility during installation, allowing you to orient it for the best fit on your specific exhaust system. The XR-1 Raceline series is a popular choice among racers for its balance of sound and power, and this muffler is made in the USA.

This is a universal muffler, so you'll want to confirm the 3-inch inlet and outlet diameters, as well as the overall dimensions (5.5-inch by 8.5-inch oval body, 34-inch body length, and 39.25-inch overall length) will work with your existing exhaust setup. No logo embossment is present on this part.
