IE Exhaust
I have their exhaust also, and that dual exit pipe is crap it really only uses the one side and the cut inside is GARBAGE.
I would either take the photo of what you want to a decent muffler shop and have them make it, or just find a tip that you like on the web or the 'bay and take that to a shop and have it made.
They can cut the hanger rod off your current dual tip to make the pipe.
What do you think of the IE Exhaust? I personally think its a little cheap, i like the sound and it was THE MOST inexpensive, but it shows.
I would eventually still like to get a JCW exhaust, but until then I will run this thing.
