I'm using a mongoose downpipe and decat with mine and doesn't seem to restrict it 8) though at some point I hope to get a 3" dump pipe and downpipe to match the system size.

thats the same as was on mine before i 'goosed' it, had something like a 5inch tail pipe, think it was a kakimoto if that helps
