x-pipe options

[ponchopwr70]

Well, I'm going to get and x-pipe and new tails for my car. I already have flowmasters 2.5" 40's and I'm going to get their 2.5" tails. My options for an x-pipe are: jegs 2.5" $85 or torq tech 3"x2.5" $225. Whats the best to get for my car its a 388 with 1-5/8 3"collector headers, dynoed at 320hp and 320tq rear wheels with crappy duals. Engine spec's are on my PTgarage pape in sig. Thanks in advance.
