Detailed Description

  • Cracked or leaking exhaust joints at the flange connection
  • Loss of original exhaust tone after component failure

This assembly is listed for the 2007-2009 Mazda CX-7, and the fitment should be matched to the vehicle’s original exhaust configuration. Professional installation is recommended for proper alignment and sealing.
