yea theres one going already. but just to save you some time... buy the RK sport 4-2-1 header.... very nice addition.. gets more attention at car shows then my supercharger does (i have the 2.4L with the rk 4-2-1 header but its the same thing for the ECO) and performs very well through out the rpms. Just i suggest after you put it on, go to your local exhaust shop and get a 2.25" or 2.5" header back exhaust put on or it will sound like crap if you just use the clamp that comes with it to clamp onto the stock exhaust
