Decided to shell out the $$bucks$$ and get a new exhaust system for my 2011 F150 with 5.0 liter V8. Ordered it from 4wheelonline.com and that was the least expensive place I could find for the aFe 409 all stainless exhaust system from the cat back. The exhaust tubes will be 3 inch diameter and the stainless muffler is supposed to be more free flowing. At about $374, it ain't cheap but ....... we'll see if I like it. The part no. is afe-49-43033. By the way, shipping is free. I called the a customer rep from aFe in Calif. and he said look to get about 10 to 15% more deep sound over the stock and a considerable amount more exhaust flow.

Congrats on the purchase. No other sound like a Ford V8! BTW, no cat-back is going to flow much more, if any, than stock as the OEM muff is pretty darn good in the flow department.
