M4 carbon slayer exhaust used on my 21 zx10 for about 1k miles. No damage no issues. Comes with all original parts and even the original box. I got a new exhaust and so don’t need this one anymore. This a 3/4 de-cat slip on. May fit other year bikes with a 3 inch diameter link pipe. Will ship but buyer is responsible for shipping. Will accept PayPal, Venmo, or zelle
