what do you think about this exhaust setup?

[2000PrixGT]

I have some brand long tube headers to a magnaflow highflow, magnaflow resonator, and to two lovely borla single in single out mufflers. no drone. But the person I got the setup from grenaded the front end of his motor chucking piston through the already thin filter in the cat, I pulled out the chunks but there was little to no filter left so i yanked that too, 3 months strong with no ses light.
