2008 F350 SD crew cab 6.4L

Has anyone added a DPF or DPF / CAT delete with a tuner to their truck?  I am seriously considering it, as my 2008 F350 is out of warranty anyway, and would like this nice truck to last, and hopefully gain some fuel economy and maybe a bit more power.  Looking at the H&S mini max and a full DPF / Cat delete exhaust.  It's obviously not cheap, about $2,000 upgrade, but I am told will increase the MPG and add some power, but most importantly save the engine, help it last a long time.  To my knowledge, Ohio does not have emissions inspections to worry about, but I was curious as to what exhaust shops can replace the stock exhaust with a delete kit, if I supply the pipes?  Any other advice / comments are appreciated in advance.  Thanks fellow buckeyes.
