I've had my Magnaflow High Flow Cats on along with my Maggie for the past 20,000 miles. I had my exhaust guy check my cats for burnout per Ten Jannetty's advice and all was clear. No damage at the time. I'll continue to check them annually to be safe. I'm about 550rwhp. Keeping my fingers crossed. We'll see. No opinion here.
