Had this on my 2025 Silverado LTZ 6.2 for about two months before trading. Not gonna use it on my 2026 because I’m getting a different system. This plugs in to the connection going to your exhaust valve and the small one clips back into the empty female connection on top of exhaust valve. It keeps the valve open like in sport mode but without having to be in sport mode. So normal mode sounds like sport, maybe even a little louder. No check engine lights. $50 and free shipping. I can take PayPal or Venmo.
