It offers a slight increase in horsepower and torque, as well as a deeper and more aggressive exhaust note. Slip-ons are generally easy to install and require minimal modifications.

When it comes to choosing an exhaust system for the Yamaha YFZ450R, there are several options available, each with its own benefits. The best exhaust system for power gains depends on your specific requirements and preferences.

One popular choice among YFZ450R riders is a full exhaust system, which typically includes a header, mid-pipe, and muffler. These systems are designed to maximize power gains by optimizing exhaust flow and reducing back pressure. Brands like FMF, HMF, and Yoshimura offer high-performance full exhaust systems for the YFZ450R.

Another option is a slip-on exhaust, which replaces only the muffler portion of the stock exhaust system. Slip-ons are generally more affordable and easier to install compared to full exhaust systems. While they may not provide as significant power gains as full systems, they still offer improvements in performance and sound. Popular slip-on exhaust options for the YFZ450R include brands like Two Brothers Racing and Pro Circuit.

Ultimately, the best exhaust system for power gains on the YFZ450R will depend on your budget, riding style, and personal preferences. It is recommended to do thorough research, read reviews, and consider consulting with experienced riders or professionals to make an informed decision.
