I looked into zzperformance like Dan suggested ( thanks) they offer a high flow u-bend delete t.o.g cat'ed downpipe made for coming off aftermarket headers.
So I think I'm going to go with the SSAC headers, into the zzp t.o.g cat'ed downpipe with o2 sensor, through magnaflow mufflers and out.

May consider adding either a resonator or resonated tips after.

Thanks for all the help.
