Black stallion

Ok so I have a 1997 k1500 4x4 5.7 and recently my drivers side donut gasket started leaking well within a week the other side is leaking I h the factory true duals with both cats then its straight piped to 45s out the back. Why would they both start leaking so close my motor and trans mounts seem good any advice ??im thinking about reworking the stock exhause with pacesetter lts and no cats with some race mufflers?
