Overview

The FortisArc Universal Muffler is a compact, DIY-friendly solution designed to fit a wide range of vehicles with a standard 2.5-inch exhaust system. With a total length of 13 inches and a 7-inch body, this pair delivers a balanced footprint that works well in many engine bays, helping you achieve a deeper, more assertive exhaust note without overwhelming noise.

Why choose FortisArc FortisArc Universal Mufflers

Built to endure, the mufflers feature an aluminum-coated surface that resists rust and corrosion in varied weather. Their internal baffle technology helps soften exhaust noise while preserving essential flow for responsive engine performance. The combination of rugged construction and a well-tuned single-chamber design makes them a versatile option for enthusiasts who value both sound and durability.

• Built-in internal baffle reduces exhaust noise while preserving engine response.

• Value-packed: 2 mufflers per order with space-saving packaging (13.4" x 9.4" x 9.1").

Real-life use cases

Whether you’re refreshing an aging exhaust, tuning a build, or simply seeking a deeper tone, this FortisArc pair offers a practical, non-prescriptive path. Expect a more noticeable exhaust character under acceleration, with a refined, controlled roar at higher RPMs. Since results vary by vehicle and tuning, consider these mufflers as a possibility for a more present sound rather than a guaranteed outcome.
