High flow cats

[Speed03.5]

Does anyone know any good sites to find some decently priced high flow cats? I'm at 142k and I'm trying to replace them before 145k

I have custom 2.5'' midpipes and resonator with stock cats. Will high flow cats go right on or will I have to weld them on/get more 2.5'' piping?
