I have done a ton of research on this. If you like the sound of an outboard boat motor go with stright pipes. If you like the sounds of the Cobra's go with the MAC off-road h-pipe. If you are going to duals get rid of all 4 cats. If you go any bigger than 2.5" pipes YOU WILL LOSE HORSEPOWER. If you stick with 2.5" 2-chamber flows it will sound darn good and gain alot of power. I put the MAC off-road h-pipe on with two 2-chamber flows and everyone thinks it is an eight it took me about 2 hrs to put it all on. Good luck and if you have anymore questions please ask.
