Borla S-Type Muffler (400497) delivers aggressive sound and premium fit for universal applications with 2.5in inlet/outlet and 5x10in body.
This Borla S-Type muffler is the same component used in Borla’s renowned S-Type systems for the Corvette C5/C6 and Mustang, providing a proven blend of performance and refined sound. Its universal design with a notched neck allows for versatile installation in custom or space-constrained exhaust builds.
Crafted from T-304 austenitic stainless steel, this muffler offers high resistance to corrosion and is built to last. The round 5-inch body measures 10 inches in length, designed to enhance exhaust flow and deliver the signature S-Type tone—aggressive yet civilized. A natural mill finish allows for customization through polishing or brushing, matching aesthetic preferences for custom builds.
The muffler's reversible design provides flexibility during installation, and the notched necks accommodate clamp-on mounting using 1-inch wide band-style clamps (not included). The internal packing uses high-temperature Continuous-Filament Fiber (CFF) acoustic material to refine tone while maintaining flow.
Proudly made in the USA, this Borla product is backed by their industry-leading Million-Mile warranty.
