High flow cat question

[AzNguy]

I want to replace my stock cat with a high flow cat. My cat back exhaust pipe is 2.25''. I went to Jegs.com and only found 2.25'' in/out cats but the piping before the cat isn't 2.25. So, does anyone know the size and/or a solution? and where I can buy the different sized In/out cat?

In all honesty, I dont think the Yaris and the term "High Flow" fit in the same catagory, lmao.
