Up for sale is an M4 Slip-On Exhaust Muffler designed for the Kawasaki Ninja ZX-6R / ZX-6R 636. M4 exhaust systems are known for improved exhaust flow, reduced weight compared to the factory muffler, and a deeper, more aggressive exhaust tone. This slip-on muffler replaces the stock rear muffler section and mounts directly to the factory mid-pipe location.
ITEM CONDITION
This exhaust muffler is used and shows visible cosmetic wear from previous use. The muffler body has several scratches and scuff marks consistent with normal riding and handling. There are also small dents visible on the muffler canister surface. These dents appear cosmetic and do not show signs of cracking or structural failure. The inlet pipe and mounting points appear intact and straight with no visible breaks. Heat discoloration is present on the pipe, which is typical for stainless exhaust components. The exhaust outlet and internal baffle area appear intact. Mounting hardware and additional brackets are not included unless shown in the photos. Overall the muffler remains usable but has cosmetic imperfections that should be reviewed carefully in the pictures.
