Has anyone had any problems after adding dual exhaust using Fenton exhaust manifold?

what kind of problems are you talking about? Only ones that I know of have been during installation, judicious use of a grinder is needed to clear the intake. Don't use the stainless steel bolts or studs for this, they look nice but get retempered from the heat and turn brown, and the threads will gall when you try to remove them. Find a good muffler shop to build an exhaust system for you, it will be cheaper in the long run for you than doing it yourself with off the shelf parts.

Had some problems with intake/exhaust manifold leaks. Eliptical hold downs don't match real well when adding a Clifford 6=8 Intake manifold and Fentons. Grinder and gasket sealer solved the problems. Had muffler shop add stainless exhaust. No probs.

I Have run into problems fitting the new repo. Fentons. I have had No problems fitting original
40's 50's Fentons. If ya are gonna use Fentons, dont forget to use the correct heat plate kit to make up for deleating the heat riser from your old stock exhaust manifold.
