It is not necessary to install a muffler if the exhaust pipe is too loud. Here are the specific details about installing a muffler on a car: 1. After installing a muffler, both positive and negative effects are equally evident. The positive result is reduced noise, less additional vibration, and a more comfortable passenger environment. The negative effect, however, is that it can restrict exhaust efficiency. 2. The engine operates in four strokes: intake, compression, power, and exhaust. For performance cars like supercars, high RPM performance is essential for pursuing ultimate power. Massive intake and exhaust require efficient methods to meet these demands, so the mufflers in supercars are designed to minimally restrict exhaust flow, resulting in less noticeable noise reduction.
