Removing the factory catalytic converters violates emissions standards in Europe, the US, and many other regions, and may also exceed legal noise restrictions in some areas. In the UK, a vehicle equipped with these will not pass an MOT inspection.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\" style=\"mso-margin-top-alt: auto; mso-margin-bottom-alt: auto; line-height: normal;\"\u003e\u003cspan style=\"mso-fareast-font-family: 'Times New Roman'; mso-bidi-font-family: Arial; color: black; mso-themecolor: text1; mso-font-kerning: 0pt; mso-ligatures: none; mso-fareast-language: EN-GB;\"\u003eInstallation typically triggers a check engine light and may cause the car to enter limp mode. To operate properly without issues, you'll need ECU coding, an aftermarket tune, or other modifications to address the sensors.
