All exhaust these days provide similar power. However, do the following if you can, this can give you better performance than usual one size all the way exhaust.

1. make sure no cat.
2/ 2 1/4" front pipe
3) 2 1/2" mid section
4. 2 3/4" rear section including muffler internal section

Usually only japanese exhaust can provide you these sizes like 2 1/4" and 2 3/4". Do more research to try source this pipes section by section as usually you can only get 1 size for the full exhuaust.
