X Tech Muffler Packing Mat 340 X 550mm

The X-Tech Muffler Packing Mat is a replacement packing material designed for relining motorcycle exhaust silencers and muffler canisters. It is suited to riders and mechanics who need to restore sound-dampening performance in a worn or burnt-out exhaust can.

Cut to size at 340 x 550mm, the mat provides enough material to service most standard aftermarket and OEM silencer canisters. It is a straightforward, no-frills solution for exhaust repacking maintenance.

• Pre-cut sheet sized 340 x 550mm — suitable for most standard muffler canisters
• Designed for DIY exhaust repacking and silencer restoration
• Can be trimmed to fit a wide range of canister diameters and lengths

Measure the length and circumference of the existing packing layer inside the canister before cutting, to avoid waste.
Remove all old packing material and clean the inside of the canister of carbon deposits before fitting new material.
Wrap the mat snugly around the perforated inner core, ensuring even coverage with no overlapping gaps that could create hot spots.
Secure the mat firmly before reassembling the canister end caps to prevent it shifting under exhaust gas flow.
Do not handle with bare hands if the mat contains fibreglass-type material — wear gloves and eye protection during installation.
Allow the exhaust to cool completely before beginning any repacking work.
After installation, run the engine briefly and check for any unusual exhaust noise that may indicate uneven packing or a poor canister seal.
