The first one in 3 sections is correct. Thus I believe they also make one that has a carbon canister that's similiar but has a few more bends of course.
Ok, according to HKS there is only one model that you can purchase and that's the 3 section HI POWER CBE. The one that is almost straight looks exactly like the one that I purchased for my Subaru years back.
The 2nd is just a generic picture of the HKS Hipower exhaust for a different car.
If you get an hks hipower exhaust for a honda or sometrhing like that, it'll look like the pic PG uses.
