Another thing I want to address is my leaking exhaust. Earlier I thought it was just the the joint between the Bosal muffler and tailpipe assy, but noise/leak still persists. Had a closer look a few weeks back at the cats and was surprised at the condition of the rear car and O2 sensors. Can’t recall if I replaced the Y-pipe as well. Replaced the rear cat and catback Bosal system around 2013, so 10 yrs ago. Will buy new NTK O2 sensors.
