You can take the stock horse off of the stock plenum or you can order a new one and get some silicon RTV. Put some silicon onto the bottom of the horse and place it on the middle of the accufab plenum and center it. Give it some pressure and wipe off the excess that squeezes out the sides and let it dry. It actually looks pretty good and people think its stock.
The reason that I did it is because cops in my area are pulling any sports/ muscle/rice cars they can and writing them tickets for moddifing their cars.
