Hello!
Looking at all options for and exhaust system for my 69 383 road runner. Its a toss up between headers and manifolds but Im leaning towards the manifolds since the rest is all stock. I'd really like an H pipe and wonder if the factory style 440 set up would work?

Thanks,
Carl


The 440 is an RB block so the pipe will be too tall for the 383.



The height won't be as bad as the WIDTH you will end up with once the 2 pipes are stuck together.

A TRUE factory style H pipe is ONE PIECE so they will be wider than the outlet placement on a 383 .
