rear resonator section (Section 2) WITHOUT the resonator (straight pipes); bolts to front section (stock or Supersprint #787512) and to any rear muffler section; 100% stainless steel. Without the resonator in place, the straight pipe will make the overall exhaust noise louder and allow more rasp to be heard.
