Unless you are planning some other really serious mods like cyl head work, cams, big bore, etc., I really doubt the extra expense of doing 4 individual pipes is hardly worth the price vs. perf increase ratio.
I believe a well designed 2>2 or 4>1 system can make as much or maybe more power than individual pipes in all but a flat out max perf drag setup.
But, then again, I'm not a pipe expert....
