RPM ATV Spark Arrestor Insert With Quiet Core

RPM 2.5" ATV Spark Arrestor Insert with Quiet Core

Keep your machine trail-legal, forest-compliant, and neighborhood-friendly without choking off horsepower with the RPM SXS 2.5" ATV Spark Arrestor Insert with Integrated Quiet Core! While open, high-flow sport exhausts deliver exhilarating engine sound and maximum throttle response, public trail systems, state forests, and national parks require functional spark containment and enforced decibel limits.

Engineered as a dual-purpose solution, this insert combines a USFS-style fine-mesh stainless steel spark arrestor screen with an internal baffled quiet core cartridge. The quiet core softens harsh, high-frequency exhaust bark and lowers overall operating decibels to comfortable riding levels, while the precision screen traps hot carbon particulates to prevent trail fires.

Precision-crafted to fit exhaust outlets with a 2.5" (65mm) inside diameter and measuring 5.5" in total length, this insert slides directly into RPM ATV sport mufflers and slip-ons in minutes, securing cleanly with standard set screws for quick removal whenever open-course competition calls.
