rear silencer/muffler

looking for a rear back box to fit newage impreza 2005.

Im looking for the most power and least backpressure that I can get.

currently have 'Jap Can' system bought off ebay with 3" pipework and 4.5" angled exit rear back box.

...but I think this set up is not producing the best power. it does however have that very distictive flat four burble on idle.

also have the second CAT removed.

Im looking for the most power and least backpressure that I can get.

Any Idea's ?
