Yoshimura · AT2
The Yoshimura AT2 Straight Premium Muffler Repack Kit is a replacement service parts package designed to restore the exhaust performance and tone that an AT2 Straight muffler was engineered to deliver. Yoshimura notes that its Road exhaust systems should be repacked every 7,000 - 10,000 miles to maintain intended function.
This kit is listed for Kawasaki Ninja-650 2017–2026, Kawasaki Z650 2017–2026, Suzuki SV650 2017–2026, and Suzuki SV650X 2019–2026 (see the fitment table below). Fresh packing helps avoid airflow restriction caused by dirty packing, which Yoshimura states can lead to lost power and degraded sound.
Materials
Built around premium packing material, this kit supports proper service intervals so the muffler can continue to perform as designed. Yoshimura explains that old, dirty packing can restrict airflow from the motor, while repacking promotes freer airflow that helps restore lost power and improves exhaust sound.
Installation
The kit includes rivets and a rivet band to support a straightforward repack process. These service parts are intended to help secure the repacked muffler assembly correctly, keeping maintenance focused on restoring performance and sound characteristics over time.
Development
To complete the service, the package includes an Alpha 2 name badge along with repack instructions. It is designed to help bring the muffler back to a properly maintained condition after repacking, using components specified for the AT2 series.
Performance
Yoshimura states that its Road exhaust systems need to be repacked every 7,000 - 10,000 miles, and emphasizes that staying on this schedule is essential for the exhaust to perform the way it was designed. As packing becomes dirty, Yoshimura notes it can restrict airflow from the motor, which may result in a loss of power and a degradation of sound. Repacking is intended to restore freer airflow, helping bring back lost power and improve exhaust tone.
