what would you like help with?
off the shelf extractors are generally all the same and only a marginal improvement over stock, any brand will do.
get the whole system done from extractors back, ie larger flexpipe, higher flowing cat, mandrel bends etc.
2.25" shouldn't be too loud with the right muffler / resonator combo.
Do you plan on doing any headwork / getting a cam etc? If so, go upto a 2.5" extractor back system.
