Customer Reviews (4.8 / 5 · 5 reviews)

Adam ★★★★★

The install was straightforward, and the stainless muffler has a deep, aggressive tone that really wakes up the Ninja 500. I can feel the weight difference from the stock pipes right away, and the power delivery feels much smoother through the rev range.

Ruby ★★★★★

Bolt-on install was straightforward, and the stainless muffler’s welds look clean even after a few heat cycles. The mid-range pull on the Ninja 500 feels noticeably sharper, though I didn’t bother with a tune yet.

Sofia A. ★★★★★

The AT2 system woke the 451cc twin up noticeably on the straights, and the stainless muffler keeps the tone deep without being obnoxious at idle. Fitment on the 24-26 Ninja 500 was spot-on, no wrestling with brackets. Took about an hour to swap and the welds look cleaner than the stock unit ever did
