In this video you can see and hear the difference between a BMW M2 F87 'Voodoo Ride' fitted with a decatted Akrapovic exhaust system and a PP-Performance BMW M2 F87 with a straight piped Fi Exhaust system. The M2 with the 'Voodoo Ride' sticker has got a ECU upgrade from RaceChip producing more than 400HP and it has also been fitted with an Akrapovic Exhaust system.The black BMW M2 has got a stage 2 CPU upgrade by PP-Performance producing around the 450HP. So which one sounds better: Fi exhaust or Akrapovic? Let me know by leaving a comment behind! Liked the video? Click the 'like' button, comment, and subscribe!
