Yoshimura Street Slip On and Race Series Alpha T Stainless Steel Exhaust for Ninja 300

Yoshimura is a Japanese brand that has a US-based production facility. Here, in the U.S. we proudly manufacture the new Alpha T Street Series Exhaust systems by Yoshimura. The Street Series Alpha T slip-on exhaust saves over half of the original part weight and unlocks 3.3% more horsepower. The Race Series Alpha T full system gives the 300cc engine of the Ninja 300 17% more peak horsepower while cutting over 6 Lbs. off the stock system weight. The products mentioned in this post feature a New Yoshimura Works Finish that looks like titanium. This coloring effect becomes visible after the motorcycle goes through a heat cycle.

You don’t need to modify anything or tamper with the bike’s emission control system if you choose to go with a street-legal A Street Series Slip-on. It has a simple bolt-on structure, but it still offers that special high-performance spirit of the Yoshimura product. And if you like to take your Ninja up for a spin on the race track, you can opt for a Race Series full exhaust system. Note that it is designed for track use only.
