Heat Riser and True Duals Help Please
I received my true duals from MAM yesterday. Removed the old exhaust and was test fitting the new exhaust. Looks like I will have to remove the heat riser assembly in order for the pipe to match up on the right side. Is this assumption correct? I know some of you have installed the duals on your car. I have a 77. Thanks for the info..

Do not use donut on pass. side. Oddly enough its all metal to metal.
Originally there was not even a gasket between heat riser and exhaust
manifold.Most people put one there just to be sure it wont leak but
I never have and no leaks. When You get everything lined up tighten
the three nuts on exhaust manifold evenly and You should be fine.
