Hi,
I haven't kept up with replacement part recommendations, anyone know what converter assy's work well on a '99 4.2L V6 4X4? I wanted Walker, but they only have them for 2WD in the V6. Same with Magnaflow. Eastern and Davico look like my only options. Any advice? Need to replace asap, for emissions. Thanks!

 

One of my friends just got their exhaust done on a 04-08 with the 4.6L. He had the factory cats replaced. I think he's going to sell them if you're interested.
