YAY!!!!!!!!! the first mod on my IS is complete, me and my freind put it on after work around 10pm, it only takes like an hour to do. i dont see why anyone has complaints about it, the relocating of a vacume cylinder thing was in an excellent spot, and the kit looks fantastic and clean. its so loud, when i cranked the car you can hear it sucking and when you rev it its so loud!!! i recomend this mod!!!
