   Studies have shown that fresh muffler packing can produce an almost 2 HP gain (from 7000 to 8000 rpm). The first place to lose packing is where the muffler canister meets the mid-pipe. This is caused by the increased turbulence where the pipe enters into the large chamber. As turbulence increases, so does the back pressure against the exhaust valves. Excessive back pressure reduces scavenging, which prevents fresh fuel from entering the cylinder. Low-to-mid throttle response suffers the most, and small displacement engines will fall flat sooner. With continued use, a worn out muffler can turn brown from the excessive heat, and as the muffler canister heats up, the packing fiber becomes more brittle and fractures at a faster rate. Avoid power loss, keep your muffler freshly packed with these Moose Competition Repack Cartridges for 4 Stroke OEM Silencers.
