Typically Denso sensors are top notch and direct fit Walker cats do a very good job. The Toyota stuff is very expensive. I have had good luck with what I have suggested.

Sorry for the mis-understading!! In the last two yrs,I change the cats and the o2 sensers twice, First time with miekie,BIG BIG mistake,about a yr ago,I change them again,this time with walkers and about 6 months ago,the o2 sensers,with bosch sensors. Now again the light is on, and the code says cats again.Why,and is the dealership the only solution, to fix it right. I just tune it up,and change the timing belt,water pump,inline gas filter,tensioners,oil seals and etc.In the area of the timing belt.the truck runs great.Love the truck,just tire sending money on the cats problem.Need someone to help me,go in the right direction, to fix the problem. Thanks!!

Your original post says you are going to change cats and sensors. Now you say you have changed them? Make up your mind and post the correct info in the order it was done. When you do I will try to help but not until then.

Agree, Denso direct fit sensors are available after market and are original Toyota equipment.
