Accurate Exhaust

When I restored my 69 Cuda M Code, I seen Accurate at Mopars at the Strip in Vegas, said he didn’t have for a Cuda but had them for a Dart, said they are the same as a Dart. So I bought them and brought them home. Fast forward 8 years and went to install and there not even close to fitting. Phoned accurate and he said Oh no they won’t fit. So he wouldn’t take them back as I had them hanging on my wall for 8 years , but I’ll sell you the right set. So I did buy the correct set and they fit very well
Sorry to hear you had a bad experience with them. I went to their shop about 6-7 years ago. He had jigs set up and a wall full of exhaust manifolds for various models. Additionally he had two styles of mufflers, one re-production and a universal model for a better price point.
I could see the head pipes being universal, but not beyond the transmission crossmember.
