Hi Zackary, thanks for initiating contact. Yes, this will likely make your car sound louder than a stock muffler, but not excessively so. Magnaflow mufflers are known for providing a deep, smooth exhaust tone, enhancing sound without being too aggressive. This muffler model features a straight-through design, which reduces exhaust restriction and can increase exhaust volume compared to more restrictive factory mufflers. If you're looking for a balance between performance sound and comfort, this muffler is a good choice. However, the exact increase in loudness will depend on your vehicle’s engine and exhaust setup.
