BLOX Racing’s all-black and standard version muffler delete kits are made from T304 stainless steel and TIG-welded for durability and reliability against cracks and leaks. Each features OEM location hangers and includes new gaskets and hardware.

BLOX Racing Muffler Delete Kits replace the OEM mufflers and greatly reduce the bulk and weight associated with them.

BLOX Racing deletes are dual-exit, quad tip designs and provide the classic Boxer rumble with a more aggressive and throaty tone.
