The TRD is nice, it's only an axle back though. And it's expensive...You could go custom and get a nice sounding exhaust, nicer than the TRD (this is coming from someone that has every TRD part available for the Gen 5, except for 3 things that i will be getting soon).
look for a custom exhaust shop in your area, or go to a muffler shop.
