I already have the stock 3 1/2" stainless system. Can I get enough flow by just doing a muffler delete? Not turning her into a dragster or anything. Am planning on installing a wildman chip and I already have K&N CAI installed. Any suggestions backed by scientific data or personal use are greatly appreciated! Thanks!

Nothing scientific here but IMHO no if you aren't going to substantially increase fuel flow then no you don't "need" a 4" exhaust. Personally I am planning on an in/out 3.5" muffler (like the walker muffler) and calling it a day.
