1961 Exhaust Manifolds and Gaskets

[baccus06]

I need to replace the exhaust manifolds and entire exhaust piping. Can anyone direct me to a more reasonably priced manifold than the$300ish ones I keep finding? Trying to do this all with a budget mindset since I'm just trying to get it running well for my Grandpa. I also am looking for a place to get the "No Blow" gaskets I have seen people talk about. I am having trouble locating those. I am also looking for a suggestion on what mufflers to put in? I am a big fan of the sound Magnaflow puts out but can't seem to find any of their 6" round mufflers around.
