Ummm, noone that I know of MAKES a dual exhaust system for a 4 cyl. Accord, you will have to get it custom made. Go to the local exhaust shop and ask them about it. The best route to go, if it will fit under your car, is: They will weld either a muffler or a glasspack right after your Cat., then there will be a Y splitter right after that into two pipes that run to the back of your car, then tips. Pick out your tips and buy them and take them to the exhaust shop, they will use whatever you take to them, or what they have, which would most likely be 3" diameter Chrome tips.
