I just bought a exhaust manifold for my runner..It has the heat riser on it.I got the riser to move very freely.Problem is that there is no spring with the manifold.So should I install without the spring,because good luck finding one.Or should I just remove the flapper and fill in the whole someway or have the flapper welded in the open position...Don't want to hear any noises from flapper...
