What catalytic converter are you guys running on your swaps. I didnt get the one off of the donor so i guess ill be buying one. Just wondering which one you guys chose?

 

I'm just running he stock one but search and you'll find some. Are you needing something for california?

 

I just eliminated my cat , and used a rear o2 simulator
you can see it in my trekker build



.

 

No, i live in washington state so nothing to worry about smog wise. Eliminating the cat would be nice. What is and where can you get a o2 simulator?

 

URD makes the rear o2 simulator

 

I don't like how loud the exhaust gets without a converter so I run one. On my 3.4 swap I used the stock one but I have bought universal high flow cats from Summit on others.


They have Cali legal types if needed and many have free shipping on your entire order. They often have sales and some brands have rebates.
