I'm trying to find out what the stock
dual catalytic converters coming off of the engine look like. I had mine replaced immediately after I bought my Jeep due to a check engine light and since then I've noticed the engine seems to be choking in moderately higher RPMs. Looking at partstrain.com, they have 2 different ones listed. A Catco and an Eastern Catalytic. The Eastern definitely seems like it would flow considerably better but mine was replaced with the Catco which is a pretty poor design. Now I'm curious what the stock is more like. Thanks!
