1. System Specs
   • For our valved systems when the valves are closed our goal is stock like sound levels. We understand that keeping noise to a minimum is often necessary for certain portions of your journey. When the valves are open, there is very little restriction and exhaust escapes uncorrupted through the tips. This provides for a much louder and more aggressive sound experience. Expect roughly 15 decibel change from quiet to loud. You can view the sound change on our youtube channel: https://www.youtube.com/channel/UCN6AyMuBD3Zaekz5MYDC5gw
   • At Valvetronic Designs we despise drone. Using the latest exhaust manufacturing methods, our systems provide a drone free experience when the valves are closed, and the most incredible raw sound when the valves are open.
2. Instillation Concerns
   • If your system is a catback you will not get a check engine light. If your system includes free flow or catted front pipes, we do not guarantee a light might be triggered. This is because changing or altering factory emissions equipment will result in a code being thrown, be sure to check your local regulations on emissions.
   • Depending on your state or country it is hard for us to say if you will pass emissions/ inspection. In most states, an aftermarket exhaust will NOT cause you to fail inspection or emissions. If you decide to alter the catalytic converter and replace it with a free flow equivalent, this will cause you to fail emissions and not pass inspection. We advise you to understand your local laws before making a decision to go free flow.
