get rid of your cats if your state allows (some will tell you to just put a good high flow cat on) but get rid of them.. run true duals.. good muffler will give you increases.. the spacers and the cold air intakes don't do jack squat for 80s-90s model pickups.. they are great for little rice burners and some of the newer muscle cars even.. but for us not even worth it.. i wouldn't even waste your money in a k&n filter.. if you have the extra money and just want it for the looks, more power to you.. there was a thread on the spacers and how useless they were for our trucks a few months ago.. was some pretty good info

 

The photo is just a bad photo-chop of what I'm shooting for. My truck is not there yet. Gathering the pieces up now and looking forward to putting them together. Almost ready for my cab swap. Thanks 6CylBill!
