Back when I was still running 340 exhaust manifolds on my 65 Barracuda, I just ran mostly stock replacement A body 340 pipes.
On the right side, when I was running a late A body 340 manifold with center outlet, a 71 Duster 340 pipe was almost a bolt in; just had to weld in a 1-2 inch section between the first and second turns after exiting the manifold. When I switched to the early rear outlet 340 manifold, had to bend a 2-3 foot section from the manifold down to the pipe. Until I put TTI headers and exhaust on it, I just ran the right pipe under the stock, uncut crossmember. It really didn't hang that low (see below), but they were only 2 1/4 pipes. When I put 2.5 inch TTI in, I notched the crossmember.

On the driver's side, I had to have a 2-3 foot section bent from the manifold down to the pipe. Stock 340 exhaust pipe from there back.
For tail pipes, Walker replacement pipes for an A body 340 fit perfectly, and I hooked them up to factory 69 Barracuda chrome tips. Even with the TTI exhaust I have now, I'm still running the last two feet of the 340 tail pipes and tips (the TTI tail pipes fit, but I could NOT get them to come out at the visually correct angle), but from there forward, it's all TTI 2.5 inch mandrel bent, with TTI headers. Sold the HP 340 manifolds for enough money to pay for the headers. <g>
