A modified exhaust system can indeed cause a vehicle to fail inspection if it is excessively loud or not street-legal. Each state, including New Hampshire, has specific regulations regarding noise levels and emissions that vehicles must comply with in order to be considered safe and legal for use on public roads. If the modified exhaust system creates noise beyond the permissible limits or does not meet legal requirements for emissions, the vehicle is deemed non-compliant.

The regulations aim to minimize noise pollution and ensure that vehicles operate within environmentally friendly standards. When exhaust modifications lead to increased noise levels that are objectionable or violate the established limits, inspectors will flag these issues during the inspection process. Consequently, adherence to these noise regulations is critical in passing the inspection.
