I suppose you could get some custom headers made up where you could add additional length of header pipes to one side of the engine. You may have to keep trying different lengths of pipe to get the noise right.
Any additional length of headers will increase lag and unbalance the exhaust.
Lots of mucking around and costs to get that boxer rumble sound.
