Hey everyone just wondered if anyone has ever had the same problem i have just had? I just installed the magnaflow cat-back exhaust on my 09 g8 gt and when i went to remove the o2 sensors from the factory exhaust the threads stripped off. I just had to order two new sensors from the local chevy dealer for about $110 a piece. Just wondering if thats a common thing?:mad:
