It looks to me like the "S-type" likely doesn't have a resonator where the original resonator(s) are on the OEM exhaust, and probably comes with mostly straight-through mufflers (i.e. like the XR1s). I think, if you're familiar with Borla's "Stinger" exhaust from the 'Vettes from a few years ago, this would be along the same lines. It's less expensive than the "X-pipe" so I'm pretty sure this is as close as we can assume at this point. The images are generic so that's no help either. Summit has some nice prices if you're in the market, IMHO.
