These mufflers are custom made for ISF's OEM Y pipe. They are the Super 10 flowmaster but without the marking on the muffler. Exact same design. All the hangers will fit onto OEM. But you'll need a muffler shop to help you install it. The extra branch piping help reduce the notorious V8 drone. Please view the videos for sound. It sounds more aggressive in person.
