Size
Race exhausts often have larger diameter pipes than road-use car exhausts. This is because a larger pipe can allow for a better flow of exhaust gases, improving engine performance. However, larger diameter pipes can also produce a louder exhaust note, which may not be suitable for road use.

Noise
Speaking of noise, race exhausts are typically much louder than road-use car exhausts. This is because race exhausts are designed to be as free-flowing as possible, which can increase the volume of the exhaust note. In contrast, road-use car exhausts are designed to meet noise regulations and may have mufflers or resonators to reduce the volume of the exhaust note.

Emissions
Another critical difference between race exhausts and road-use car exhausts is emissions. Race exhausts are often designed to produce as little backpressure as possible, which can increase the amount of pollutants released into the air. In contrast, road-use car exhausts are designed to meet emissions regulations and may include catalytic converters or other emissions control devices.

In conclusion, a race exhaust differs from a road use car exhaust in several ways. Race exhausts are typically made from better materials, have larger diameter pipes, produce a louder exhaust note, and may not include emissions control devices. While a race exhaust can improve the performance of a racing car, it may not be suitable for road use due to noise and emissions regulations. Therefore, choosing an exhaust system that meets your needs and preferences and complying with local regulations is important.

Here at Profusion Customs, we have built many race exhausts and are well-experienced in how they should be made, so if you have a race car, come and talk to us.
