Help! 370z weird exhaust sounds

fuentes2s · 08-07-2022, 10:19 AM

my temps have been extremely high. Usually 180-200 average. Lately theyve been 220-250 when I run it hard. Could it be a blocked catalytic ?

Oil temps? If so, that is about normal for a 2012 with stock heat exchanger. Even with an 34 row oil cooler they can get that hot if on track or in the mountains on a curvy road.
