I installed the Vick's manifold and muffler about two weeks ago.
I had to remove the A/C, it would not fit.
I had to remove the Alt to install it and the Alt re-installation was tight. We had to re-shape the back cover on the Alt to get past the manifold piping. The Alt cooling line will not fit.
I'm still working out the spring/hanging details and I got a ticket in NYS for the volume. I'm considering a silencer but Vick's has provided a letter attesting to the appropriateness of the muffler.
Throughout it all, Matthew at Vick's has been at the ready, providing feedback and guidance. Great support, I'd buy it again.
I can provide some pics if anyone wants some specific shots.
