Anybody know where to get a good exhaust complete manifolds back at a do it yourself price?

 

Define "good". Also define "do it yourself price".

You can get a factory reproduction dual exhaust set from companies like Gardner. They are not cheap, but they install just like factory (bolt-in only). The repro pipes will be 2.25" head pipes and 2" tail pipes.

Aftermarket A-body exhaust sets are available at 2.5" and larger. All of them will require some fabrication skills to install, including welding. Your call on your skills and wallet.

 

Waldron's or Classic exhaust offer full DIY systems at reasonable prices. You would not need to weld them, but any exhaust system may require some tweaking.

 

"Pipes Exhaust" company sell down pipes to get you back to right in front of the cross member then there are kits to get you the rest of the way back.
From what I heard trumpet tail pipes exit in the wrong place???
