Got a 71 GMC swb, sbc with 465 trans. Bought a JCWhitney(LOL) exhaust kit, years ago. 2 1/4" pipes. Have replaced mufflers twice, front pipes still great. Tailpipes now perforated.

At some point I bought another kit, but it was different than the first and is not as simple.

May get a local to make tailpipes.

Also have a 71 K20 sbc auto, thinking of what to put on it for exhaust. It has no manifolds, but as I understand it the drivers side is straight dump, the passenger is a slant back.

I also have a set of large ram horns (2 1/2") from a 64 327/365 HP but they are straight drops. Just looking for ideas and a plan with few headaches. I will look at your suggested parts at summit. Also like the chrome new manifolds from Jegs.
