It is well known that the Primary cats are a major restriction point on the E9X M3. There are a number of solutions on the market including a full X Pipe which removes the primary cats or Primary Cat Delete/Test Pipes.
Primary Cat Delete/Test Pipes are designed for those who do not want to go the full X Pipe route and are happy to modify their existing X Pipe. It is the most cost effective way of releasing power from this car.
Our Primary Cat Delete/Test Pipes are the first in the market to use a slip on and clamp solution. This provides a solid/tight fit without the need for welding. Gains are 20 BHP and 20 lb/ft torque. An ECU Remap is required to remove CEL and provides an additional power gain over and above the test pipes alone. Please see the dyno graph.
2x new gaskets are supplied
