Default Cats performance

Hey all,

I currently have Headman LT's/No Cats to a 3" offroad Y pipe that goes to a 3" SI/SO muffler dumped before the axle.

Would there be a major difference in power loss IF ANY by switching to highflow cat converters?

Only highflows i know of is Magnaflow. Should i go with this or do you have any other recommendations?

Thanks.

No, I see no problem as long as you don't go too large on the inlet and outlet diameter.

Gotcha!

So i would look for a 3" Inlet/Outlet since that is my current piping size.
Looking at some part numbers it looks like there are no threaded ports. So i have to have 02 bungs welded in for where i want to put in the 02 sensors?

Bingo! Bungs welded in close to factory locations would be ideal, that or some of those spark plug defoulers if you place them in another spot.
