quad exhaust =)
I always thought the double tip would look in the oval cutouts of the AP2. I made a track exhaust for my car with straight pipes with this look a while ago. I think it looks great and your staggered tips are a nice touch 
Here's a quick shot of mine with the track exaust on. They're just monza tips though.
