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.
