Dont waste your money on another exhaust even if th yoshi is 200$ more it pays off you are paying for top notch quality. Very silent jet so powerful
The RS-2 is a really versatile and very potent exhaust; it is one of Yoshimura's most popular off-road exhaust systems and has proven its value on the race track for years. It is basically an evolution of the original Yoshimura TRC design but with a slightly different (pyramidal) shape that features increased volume. The volume enables a quieter system and larger core, which in turn increases power and power delivery. With gains throughout the powerband and the durability of high-grade stainless steel mid-pipe, you can't go wrong with this system.
