NOT ROAD LEGAL 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 remov es 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 Show more
