Muffler Insert, for 3 Bolt Collector, 2 OD, 13-1/2 Long

EMPI Muffler Insert for 3-Bolt Collector - 2" OD x 13.5" Long

Quiet Your Baja Stinger

This 13-1/2 inch muffler insert is the ideal solution for air-cooled VW owners looking to reduce the aggressive bark of an open exhaust. Designed specifically for Baja-style stingers, this baffle features a serrated inner core and a high-quality fiberglass wrap. This combination effectively disrupts sound waves and absorbs high-frequency noise, providing a more manageable exhaust tone for street driving or noise-restricted off-road areas.

Fitment and Specifications

This insert is engineered to fit 3-bolt collector systems with a 2-inch outer diameter. It is a direct fit for EMPI stinger part numbers 00-3377-0 and 00-3382-0, commonly found on Baja Bug exhaust systems. The 13.5-inch length ensures maximum contact area for sound suppression while maintaining the flow characteristics required for performance engines.

Pro Tech Tips

Secure the Insert: To prevent the baffle from vibrating loose or being ejected under high exhaust pressure, we recommend securing it with a small self-tapping screw or a localized spot weld. Always drill a pilot hole through the stinger and the baffle collar for a clean installation.

Monitor Fiberglass Condition: Exhaust heat and moisture will eventually break down the fiberglass packing over time. If you notice your exhaust getting progressively louder, inspect the insert. Re-wrapping the core with fresh exhaust packing can restore its original sound-dampening properties.

Optimize Backpressure: Installing this baffle adds a slight amount of backpressure compared to a completely hollow stinger. For many street-driven 1600cc to 1914cc engines, this slight increase can actually improve low-end torque and throttle response, making your VW more driveable in traffic.
