FortisArc 2.5" Center-In/Center-Out Single-Chamber Muffler Pair — 13" Length, Aluminized Steel, Deep Aggressive Rumble

These are a pair of FortisArc 2.5" center‑inlet/center‑outlet single‑chamber mufflers built from aluminized steel to deliver a deeper, aggressive exhaust note with easy weld or clamp installation.

If you want a straightforward sound upgrade for a truck or full‑size pickup without complex fabrication, this dual pack provides two identical mufflers engineered for bold acoustics and durable road use. Each muffler measures 13" overall (7" body) and accepts 2.5" diameter piping at both inlet and outlet. The design emphasizes a low, rumbling tone produced by a single chamber and internal baffling, while the aluminized core and silver spray finish resist rust and weather so the components hold up through seasons and mileage.

How loud and what kind of sound will these mufflers produce?

They create a deeper, aggressive rumble rather than a high‑pitched or raspy tone. The single‑chamber geometry with internal baffles focuses on low and mid frequencies for an authoritative road presence that stays controlled under cruise.

• Single‑chamber with internal baffles for deeper low‑end sound
• Designed to reduce high‑pitched droning compared to straight‑through designs
• Pairs provide consistent dual‑side balancing on V‑type engines
• Not a glasspack — tuned for muscle rather than extreme volume

Will these fit my vehicle and how are they installed?

Each muffler has a 2.5" ID inlet and outlet and a compact 13" total length (7" body), suitable for many full‑size trucks and pickups with standard exhaust routing. They are marked "INLET" to prevent orientation mistakes and accept either welded or clamp‑on attachment according to installer preference.

• 2.5" center‑to‑center inlet/outlet openings for common exhaust piping
• 13" total length, 7" body, 9" width x 4" height footprint
• Weldable seams or clamp‑on mounting for flexible fitment
• Sold as a pair for dual‑side or replacement installations

How durable are these mufflers in real‑world conditions?

The core is aluminized steel with a silver protective spray that helps resist corrosion from road salt, moisture and exhaust condensation. Welded seams and a robust baffle structure extend service life versus cheaper, thin‑metal alternatives, making the pair a practical choice for work trucks and daily drivers.

• Aluminized steel construction for improved rust resistance
• Silver spray finish adds a protective layer and aesthetic uniformity
• Welded option for permanent installation; clamp‑on for replaceability
• Package weight and size optimized for shipping and storage

Who is this for? Installers, enthusiasts and truck owners looking for a no‑nonsense, value‑packed way to add a deeper exhaust tone and improved presence without extensive fabrication. The FortisArc muffler pair suits anyone who wants controlled aggressive sound on a full‑size pickup, needs corrosion resistance for mixed weather use, and prefers flexible mounting options for either permanent or reversible installations.
