You're in unknown territory here by sticking with stock exhausts. Stock jetting, while fat and rich below 4000 rpms becomes lean as a bone once the motor starts making stride. If it didn't, the catalysts in those stock pipes would burn like the surface of the sun!
While you certainly can rich it up a bit, its unknown how big a jet you can go before you start to encounter melting plastic and the possibility of a burnt valve!
If it was me...and it has been... I'd blow a few bucks on a nice set of pipes or in the least do some surgery on the stockers. Its possible to cut the welds on the exit side and extract the cats, then weld them back up. Cheapest and a good way out imho unless you're willing to toss on a set of FMF's or Akras ( have Akras
