Now you can have the over-the-top power and torque of open headers and still meet all of your sound requirements. These 18-gauge steel exhaust inserts from Car Chemistry fit directly into your header collectors and reduce sound output without restricting power. The 2-disc inserts are for racing applications and meet NHRA noise requirements, while the 3-disc inserts are for use on street/strip vehicles.
