I have the ART exhaust on my car. It bolts to the stock manifolds (or JBA headers) and you could get it with or without high flow cats. The ART is all 2.5in mandrel bent. You also had your choice of aluminized piping or stainless steel piping. The system used an X-pipe right around where the 3rd cat would be. It used rear mounted mufflers (like stock). On my car I had JBA Headers, no cats, and I had Dynomax chambered mufflers out back. This sounded pretty good but i wanted something louder/more agressive so I had the X-pipe removed and put in a mid mount magnaflow tru-x muffler, and removed the rear mufflers and replaced them with some long chrome exhaust tips. I think it sounds pretty good, but some argue with me that it might be a little too loud. Hope this helps.
