I dunno, it looks a lot like my HKS Hi-Power i've got on my eclipse. They do make different sized mufflers, you know. The only thing i'm not sure on is that it doesn't look like that would come out at an angle. I thought all the Hiper / Hi-Power exhausts came out at an angle N1 style, but maybe they don't on integras? I would ask the dude to take a picture of the laser engraved muffler tip to be sure.
