After 208K miles, seems the bank 1 converter on the Silverado has finally given up with bank 2 not far behind. Verified it using my scantool and sure enough, the post cat (sensor 2) voltage is mirroring the pre cat (sensor 1) voltage.
I'm wondering if anyone has used the bolt-in/direct-fit converters from Magnaflow on their GMT-900 truck/suv? Cost is $766 vs $1200 for the OEM part.
