peastorm 2.5" Valved Muffler Electric Exhaust Cutout Kit — Remote-Controlled 2.5-inch Glass-Pack Cat-Back

The peastorm 2.5-inch valved muffler electric exhaust cutout kit lets you switch between loud and quiet exhaust tones at the press of a remote, providing three distinct sound modes for street, track, or daily driving.

This complete 12V cat-back style system combines a straight-through valve with an internal glass-pack muffler so you can tailor exhaust flow and sound without swapping components. The package includes a waterproof actuator, two remotes (primary and spare), and all mounting hardware required for most installations—backed by a two-year warranty. Before ordering, confirm there’s adequate clearance beneath your vehicle; the kit is designed for universal fitment but may require minor adjustments for tight spaces.

How does the three-mode sound control work?

The kit offers Fully Open, Partially Open, and Fully Closed positions that change the exhaust path. Fully Open routes gases straight through the valve for maximum flow and an aggressive note. Partially Open produces a balanced, sporty rumble by mixing straight-through flow and muffler routing, while Fully Closed sends exhaust through the internal glass-pack for quieter operation.

• Fully Open: direct flow for louder, freer-breathing exhaust
• Partially Open: blended sound for everyday performance
• Fully Closed: routed through glass-pack for reduced cabin noise

Is installation difficult and what’s included?

The kit arrives with the valved muffler, waterproof actuator, wiring, two remotes, mounting clamps, and hardware so it’s ready for bolt-on or weld-in installation depending on your preference. Basic tools and mechanical familiarity are required; an experienced DIYer or a professional exhaust shop can complete the install. Wiring follows standard 12V actuator hookups and the remotes use a simple pairing process.

• Included: valved muffler assembly, actuator, wiring harness, 2 remotes
• Mounting: clamp-ready with optional weld points for permanence
• Support: customer assistance for fitment questions before purchase

Will this affect performance or fuel economy?

When the valve is Fully Open, exhaust back-pressure is minimized which may slightly reduce restriction at high rpm, while Fully Closed increases back-pressure similar to a conventional muffler. Changes are vehicle-dependent and typically focus on sound rather than significant power gains. The kit is engineered to balance acoustic control with safe exhaust flow characteristics.

• Open mode: lower restriction, crisper exhaust note at high rpm
• Closed mode: quieter operation with conservative back-pressure
• Partial mode: compromise between sound and flow for daily driving

How durable and weather-resistant is the system?

The actuator supplied is rated waterproof for reliable operation in wet conditions, and the muffler construction uses corrosion-resistant materials intended for road use. Electronics are sealed to minimize exposure to moisture and road debris. The kit’s two-year warranty covers manufacturing defects under normal use.

• Waterproof actuator for all-weather reliability
• Sealed remotes and wiring for outdoor exposure
• Two-year warranty against defects

Who is this for: The peastorm 2.5-inch valved muffler electric cutout kit is aimed at drivers who want flexible exhaust sound control without swapping hardware — ideal for performance enthusiasts, weekend track-goers, and commuters who need noise management. It suits DIY installers and shops looking for a compact, remote-operated valved solution compatible with many cat-back configurations.
