Um no i did not. You can contact (myzislow) and ask I already called HKS and they told me that i have to have bought it through a dealer and that i cant get a sticker if i didnt. Yes im talking about the actual hard pipes(tubing) that are by the plenum. They do have a carb sticker. I knwo they dont affect the emissions but its aftermarket and they are making a big deal out of it. Same thing with UD pulleys. I called and they told me that basically they are illegal :-(. That they cant do anything about it. Really sucks so i hope someone will come foward and help me out here T.I.A Daniel leon
