If you care about performance at all, or plan to do bigger upgrades in the future, crunch-bent exhaust piping is stupid. I don't see how ridges of metal jutting out into the exhaust flow would be just as good as nice smooth bends. Magnaflow mandrel bends are cheap, and any muffler shop can put together a good smooth system for not too much more that a crunched pipe.

You'd probably be best off with the 2.25" piping, wushu, assuming you don't have any big mods.
