Can I use the Racing Beat header and retain the stock cat converters?
No. The Racing Beat header cannot be used with the stock cat converter(s). The tuned-length primary tubing does not allow adequate space to utilize any of the stock cat converters. Although it is possible to install an aftermarket cat converter in place of the presilencer unit, this approach is technically not emissions legal. Why use a header instead of the cat converter replacement pipe (downpipe)? The header is optimally suited to perform on an engine with upgraded intake or fuel injection system. A high performance street, street ported, or race engine will benefit from the more efficient exhaust gas flow of the header configuration. Will the 6-port actuators function with after the header is installed? Yes, the 6-port actuators are operated by the back pressure from the pickup tube on the Racing Beat presilencer. If you decide to forgo the presilencer and install a “straight pipe” or aftermarket cat converter, make certain that a pickup tube is incorporated into your design or you
