Harley-Davidson X440 / X440 OBDII / X440T Muffler Cover 2 Matt Axis Grey OEM | HDH18318-RAA-000N

Replace a scratched, faded, heat-marked, or damaged exhaust trim piece with this genuine OEM muffler cover for Harley-Davidson X440 series motorcycles. Part number HDH18318-RAA-000N is the OEM Muffler Cover 2 finished in Matt Axis Grey. In buyer language, customers are most likely to search for this part as the silencer cover, muffler heat shield cover, exhaust cover, or silencer shield.

This is a model-specific exhaust outer cover piece used to maintain the clean factory finish of the bike’s muffler area. It is ideal for bikes where the original cover has been scratched in daily use, damaged in a tip-over, dulled by age, or spoiled by cosmetic marks that make the exhaust side look old before the rest of the motorcycle does.

The wording on this page is intentionally buyer-friendly. Instead of relying only on factory naming, it uses the terms riders actually search when looking for a replacement exhaust-side cover: muffler cover, silencer cover, and heat shield cover. Harley’s current X440 T page also highlights the updated exhaust with a new heat shield and end cap, which supports strong buyer search interest around muffler covers and exhaust shield parts on the X440 family.

Confirmed fitment: Harley-Davidson X440, X440 OBDII, and X440T. This SKU is not confirmed here for X440X or Hero Mavrick 440, so please do not assume cross-fitment across all 440-family motorcycles.

This listing is for one Muffler Cover 2 in Matt Axis Grey only. It is not the full silencer, not the complete exhaust assembly, and not a universal heat shield. Please match the part number, finish, and exact requirement before ordering.
