Thanks Spooler, I forgot to add in the OP that I’ve noticed the coolant weeping out after a WOT pull. Nothing too crazy just a quick 0-60 and the actual coolant that is at the bottom of the plastic pan is drops maybe less than an ounce. Do these stock cats fail frequently? My car just hit 40k miles.
