All header systems have three basic components: a flange primary pipes and a collector. The design and production quality of each of these components has an effect on a headers performance and service life.flange-to-engine sealAny distortion in the plane of a flange surface can cause exhaust gas leakage. DynoMax precision quality means flatter truer flanges for a better seal.port siz eHeader flange ports should be as large or larger than exhaust ports. Any blockage at this connection will restrict flow.primary tube diameterTube diameter affects flow rate. Flow rate affects where torque peaks occur in relation to engine speed. Smaller diameter tubes result in the torque peak occurring at lower rpms which is perfect for RVs. Larger diameter tubes deliver peak torque at higher RPMs for racing. primary tube lengthPrimary tube length effects torque curve. Adding length adds torque below-the-peak and reduces it above-the-peak. Shortening primary tubes adds torque above-the-peak at the expense of below-the-peak torque.tube bendsAny constriction at bends results in restriction of flow. DynoMax primary tubes have mandrel bends for up to 35% better flow than ordinary compression-bent torque.header finishFor decades header enthusiasts have had to put up with painted finishes which rapidly burn-off and lose any ability to protect. DynoMaxs optional Jet Hot ceramic coating not only provides long lived protection it actually enhances header performance. This exclusive finish is only available from DynoMax. It coats headers both inside and out.
