Assuming that is PVC then its going to be quite stiff when its cold and is not recommended for use in temperatures environments above 70 degrees Centigrade. I think you would be better going for the silicone hose recommended earlier in this thread. If you do use it keep it well clear of the exhaust manifold.

Go stainless next to exhaust, relatively cheap and it don't melt .
