Piecing together a stock-ish exhaust.

[Jimal]

Okay, I'm fed up with my exhaust system. Right now I have 2.5" duals that start with stock 2' rams horns and end at a set of fabricated Thrush mufflers I installed last summer. Its loud, it smells, it leaks, it doesn't fit quite right, and unless I invest in headers or Corvette manifolds isn't going to breathe all that well. And besides my basically stock, low-compression 400 doesn't need the breathing that headers and duals provide.

So now I've set out to put together a stock-ish exhaust system. My truck very obviously isn't a restoration project, so I'm not concerned with it looking original. To that end I'm starting with the Walker Exhaust catalog.



Based on what part numbers are listed, only some pieces are still made. While the muffler, tailpipe (if I go that route), gaskets and hangers seem to be generally available, the midpipe doesn't seem to be made anymore, and the y-pipe isn't currently in stock anywhere...

Then I found a place that claims to have four of the y-pipes in stock.

I took a flyer and ordered one, but I'm expecting it to either not actually be in stock, or be something unexpected. What I did find interesting is that they use the same y-pipe on full-size sedans of the era. The Walker P/N 42087, crosses over to a '63 Impala sedan with the 283.

If a y-pipe shows up in a few days, I'll start ordering the other components, get everything installed (or at least mocked up) and bring it to a local muffler shop to have a midpipe bent up. Unless someone can point me toward a source for that component.
