Alright here it is I am new to decking out my truck but I want it to perform better. It is an 05 lariat and I am thinking of putting a roush cai , magnaflow 16518 exhaust system, and debating on an edge evolution or gryphon .... do you guys think this will do me good for performance and fuel economy

Yes it will help both. If you get the cai, get the gryphon so that you can get a custom tune for the cai. I won't get into the possible lean issue debate about cai, but to get the most out of it, a custom tune will be the way to go. Not sure if that magnaflow is a system or not, but if so, just buy a muffler and have a local shop weld it in with their piping.
