Evolve Stage 2 Remap With Cat Delete Pipes - BMW E90 | E92 | E93 M3What Imran thinks: "This is the most cost effective way of improving the performance of your E9X M3. These cars lack low down torque despite being a 4. 0 V8. The combination of the test pipes and our Stage 2 ECU tune really wakes the car up providing a noticeable gain in low down torque and upper end power. Releasing some extra V8 sound is also very welcome!" NOT ROAD LEGAL Dyno not included This is for installation at Evolve and includes installation
