The FMF MegaBomb is an exhaust header for the 2026 Ducati Desmo450 MX and Desmo450 EDX. It forms the front section of the exhaust and can be paired with an appropriate FMF slip-on silencer, which is a separate component. This is a header, not a complete exhaust system.

Features

• Designed to improve low-to-midrange response while retaining useful upper-range performance. These are general MegaBomb design characteristics, not verified gains for the listed Ducati models.
• The chamber acts as a pre-silencer to help reduce exhaust noise.
• Designated for closed-course use only.

Specifications

• Material: stainless steel.
• FMF states that MegaBomb headers can reduce exhaust sound by up to 1.5 dB. This is a general claim, not a verified result for the listed Ducati models.
