I'm hoping to do the exhaust all by myself with Walker parts.
I have a 1971 Chevy 250ci with stock manifolds mounted in a 1965 C10 frame. Walker makes the correct pipes from the manifold back.
Walker front pipe is #48111 and the rear pipe is #44144. All I need to do is shorten the front pipe about 11" because it's made for the long bed and I have a short bed.

The rear pipe has not yet arrived, so I haven't confirmed the ID of the rear pipe but it looks to be slightly expanded to accept the muffler from the photos I've seen.

The muffler options seem numerous. I don't want a loud sound. A stock looking muffler would be fine. Any recommendations?

Here's the front pipe and it has a tulip end for the manifold. I've read that it eliminates the need for a donut.
