  • The factory midpipes and downpipes altogether vary lengthwise by almost a foot and a half, creating unevenly spaced sound pulses
  • R&D at AA solved this uneven sound by evening out the length of each midpipe
  • The AA EL is also lighter weight than factory midpipes
  • Recommended by AA to run the resonated version if you have catless downpipes
  • According to AA, the results are a tad louder, but deeper sound
