FMF Factory 4.1 Stainless Steel Mufflers might not be made of anodized titanium like their big brothers, but they certainly still pack a punch when it comes to upgrading the performance of your four-stroke machine. These beauties still feature all the same performance upgrades as the anodized titanium model, they just come in at a slightly heavier weight, due to their stainless steel construction. They still feature the same carbon fiber end cap, though, and the natural finish to the canister is a work of art in its own right. Enhanced throttle response and performance gains throughout the entire RPM range are just some of the features of the 4.1 Stainless Mufflers, so if you're looking at upgrading your dirt bikes performance without completely breaking the bank, these are going to be a solid option.
