Just stick with the single 3" exhaust, you don't need poly mounts, and you don't need ceramic coating. Ceramic coating will help a bit with under hood temps and make the headers last longer. True duals will net you nothing more than headaches and extra weight. If you want to get loud now and then put in an electrc cutout right before the axle. I'm still running a 3" catback and was trapping almost 120 in the 1/4 before my trans started to slip. Some people have had good luck with the stainless steel Ebay headers.
