i would have got rid of my rear cats, use hooker headers and tips maybe true duals. theres a clear powder coat that is for high temp and once its on it wont even stick to its self.so meaning no more ruined tips from mud.rightnow i have tar all over mine and the side of my truck from the road. http://www.holley.com/data/products/pictures/large21431.jpg

 

magna flow's supposed to have realy good high flow cats for $100. dude at offroad shop put on his expedition that has super charger made a big difference on sound and mid and uper power . 4 cats is to much nonsence. and he still runs the stock injectors and coils. igot headers because of one of my manifolds were worped
