Frequently Asked Questions (FAQs)
1. What does a longer exhaust pipe do?
A longer exhaust pipe helps to reduce the noise level of the exhaust system. Having the exhaust pipe extend all the way out the back of the car makes it quieter compared to side exhaust. Some believe that routing both pipes to the driver's side of the car helps divert sound away from the sound meter.
2. Is flex pipe OK for exhaust?
Flex pipes can handle vibrations better than other exhaust pipes, but they are prone to cracking over time. They can also get damaged when the vehicle bottoms out and the pipes hit or scrape against the road surface.
3. Do bigger exhaust pipes increase horsepower?
Changing the size of the exhaust pipes in your vehicle can lead to increased performance. Bigger pipes allow for better airflow, resulting in improved horsepower and torque.
4. Are long exhaust pipes illegal?
Exhaust modifications are only illegal if the noise emitted exceeds 95 decibels. However, it's important to check local regulations and smog laws, as they may have additional restrictions. All vehicles must have mufflers, and bypasses, cutouts, and whistle tips are not permitted.
5. Does the length of the exhaust pipe affect the sound?
The length and diameter of the exhaust pipe can affect the sound of the exhaust. A longer and narrower exhaust tip can restrict exhaust gases, resulting in reduced noise levels, similar to a muffler.
6. How long will a flexible exhaust pipe last?
The lifespan of a flexible exhaust pipe depends on factors such as the material, manufacturing quality, and usage conditions. High-quality flexible pipes manufactured to strict standards can last for many years.
7. How can I make my exhaust louder and deeper?
Increasing the bore of the exhaust pipe, but not by too much, can make the exhaust louder and deeper. Wider pipes reduce obstacles and allow for a louder sound. However, it's important to consider local noise regulations.
8. What kind of exhaust gives the most horsepower?
A cat-back exhaust system improves horsepower and performance by allowing better airflow. This reduces the strain on the vehicle and increases the flow of air, resulting in improved horsepower.
9. How can I make my exhaust sound deeper?
To achieve a deeper exhaust sound, you can consider installing a free-flowing performance muffler that incorporates hair or fiber-like material for sound absorption. Brands like Borla or Magnaflow offer mufflers that provide a deeper tone compared to stock mufflers or those with chambers or baffles.
