Vehicle Mod Laws in Nevada

Replacing the exhaust system is legal in Nevada, but a muffler in good working order is required and cutouts or bypasses are prohibited. There is no statutory 'no louder than stock' rule — the standard is that the exhaust must not produce excessive or unusual noise.

Nevada bars any sign, poster, or non-transparent material on the windshield that obstructs the driver's clear view, with one exception: a 6-inch-square area in the lower corner farthest from the driver. Tinted transparent material is allowed only on the uppermost portion with its bottom edge at least 29 inches above the undepressed driver's seat. Because the material must be transparent, a printed or opaque banner is not legal in Nevada — only a clear tint band.
