I'm looking to get magnaflow cats for my 07. Can anyone help me find the setup I need for this? I'm not really sure what I need. Do I need a setup with a y pipe or can I just get the cats and cut the old ones off. Also I have my stock 2.5 inch pipe going onto a 3 inch exhaust so a little confused on what I need

Get two Magnaflow 94306's or 94106's and weld in place of the old cats. No need to change the Y pipe or anything else if you already have it.

You just cut them right out and that will be good?

Tprimo15

And which one would be louder sounding

Tprimo15

Haha also do those hold 02 sensors in them

You will have to weld o2 bungs in those. They do offer ones with bungs. I think 94116 but you will have double check that.

Yeah I just looked them up one has a hole for the sensor one doesn't

So with these cats u can just take the old ones out and put the magnaflows in?

It's not plug and play. Those are universal replacements. They will require cutting/welding.

Yeah but I mean there's atleast a hole to put the o2 sensor in then weld ya know
