CAT help

[Alerosaint]

Hey guys I am looking to purchase a high flow cat but after looking up some on Magnaflow's website its not as easy as clicking on a cat and buying one. There is a slew of options as in the different series they offer then the different cat "functions" in the series like 2-Way, 3-Way, or 3-Way + Air

All I want to know is which magnaflow high flow cat I can buy that will perfectly replace my stock cat, offering a spot for my 02 sensor and throw no codes. Thats it. Also which size would be better for the MP45 a 2.5" or 3"?

i'm pretty sure, unless your running a HUGE turbo, you shouldn't go bigger then 2.5"

as for the other stuff, its outta my league to comment on.

2.5"
No cat or a regular cat is fine. It's been dyno proven removing the cat does not increase performance hardly at all. Just pick up a universal one from AutoZone for like $68.
