💥Installing after-market headers on a naturally-aspirated engine can provide a moderate increase in power.
🔧Headers help with exhaust scavenging, improving airflow and overall engine performance.
💰After-market headers are a cost-effective way to enhance performance compared to other modifications.
🔊Headers produce a deeper and more aggressive exhaust sound, enhancing the driving experience.
👨🔧Installing headers can be a fun and rewarding DIY project for car enthusiasts.
How much horsepower can I gain from installing after-market headers?
—The power gains from after-market headers vary depending on the specific engine and header design. Generally, you can expect a moderate increase of around 5-10 horsepower.
Are after-market headers expensive?
—Compared to other aftermarket modifications, after-market headers are relatively affordable. Prices can range from $200 to $1000, depending on the brand and quality.
Do after-market headers affect the sound of the exhaust?
—Yes, after-market headers can change the sound of the exhaust. They typically produce a deeper and more aggressive tone, enhancing the overall driving experience.
Can I install after-market headers myself?
—Yes, installing after-market headers can be a DIY project for car enthusiasts with some mechanical knowledge and the right tools. However, professional installation is recommended for those who are not experienced with exhaust modifications.
Do after-market headers improve fuel efficiency?
—While after-market headers can improve engine performance, they typically do not have a significant impact on fuel efficiency. Other modifications, such as tuning and intake upgrades, may be more effective for improving fuel economy.
00:00We install after-market headers on a Miata and Dyno it to determine if the performance gains are worth the cost. Though we didn't hit our target of 5 horsepower increase, the headers improved mid-range and upper-range torque. The installation was easy and the headers added a cool look and great sound. Overall, we believe the headers were worth it.
08:35We Dyno the Miata with the new headers and find that it only gained around 2 horsepower. However, the headers improved mid-range power and created a unique sound.
10:05We conclude that although the horsepower gain was not significant, the headers were still worth it due to the overall improvement in performance, sound, and aesthetics.
