We have no idea what size you have. What have you swapped? Do you have the SLE exhaust, or L67? Did the exhaust swap with the drivetrain? Are you aware deleting the Cat will make you lose some low-end torque and is illegal? And that any member here that turns you in will get a $250 reward? As well as any shop that notices it'* missing?
I can tell you with certainty you will not be happy with the loss of low-end torque. And your current mods don't spell cat outflowing.
(can you tell this is a pet peeve of mine?
