Your a/f ratio will not change with or with out a tune. The o2 sensor is still reading the same gas as it was before. The only problem that can arise is a CEL for the o2 test which will do absolutely nothing to the performance. It only means the o2 is taking longer then normal to heat up due to it being moved further back. You can get it removed with a tune.

the only long tubes i have seen for 4.6 were made by Pacesetter.
they offer the crappy painted steel and a ceramic coated steel but i had a set of ceramic coated shorty headers on my 97 f-150 and was not impressed with how they looked only about a yr old.
i never had any problems with cracks or leaks but they did not look like i thought they should for what they cost.
i will only buy stainless steel from now on !

I have had BBK stainless shorties on for 10 years with OEM gaskets and have never had a problem and a decent difference over stock. For the money it was worth it. They bolted right in. Long tubes will require a complete change in the exhaust and cost a butt load more to do.
