Well, personally I think it's worth the money. You can't have an efficient engine if your intake and/or exhaust is too restrictive (which is what the Yaris was cursed with out of the factory). If you wanted to replace your exhaust, I'd start with the axle-back so that you can find which kind of sound you like. Then you have the option of either going with the Nitto midpipe (available from microimageonline.com) or custom-fabricating your own midpipe (warning: the Nitto midpipe does not have any catalytic converters; they're just resonators). And you know, I would recommend replacing the header. The stock design is rather convoluted and doesn't lend itself well to a good exhaust flow. For this you have many options: TRD (expensive as all hell), Megan, DC, Thunder, DME, or, again, custom make your own. If you plan on doing more performance modifications to your car, a good exhaust system is pretty much invaluable. Hope that answered your question well enough :D
