Most listings show muffler baffles made from steel, stainless steel, or galvanized iron.
Listings indicate muffler baffles reduce overall noise and specifically tame deep or “deep note” tones as exhaust gases pass through the muffler tube.
Some listings show insert lengths of about 13.5 cm (5.31") and 15 cm (5.91"), and list outer diameters such as roughly 3.7 cm (1.46") and 5.1 cm (2.01").
Many listings sell single baffles, while some offer inserts in 2‑packs.
Weights in listings range from about 2.19 ounces for small inserts up to roughly 1.88 pounds for larger replacement baffles. Overall dimensions vary widely—from a few inches for small inserts to about 22.5 inches for larger parts.
Most listings describe a silver‑tone metal finish and note constructions such as stainless steel or galvanized iron.
