no good news for the 73
 

I was out checking it over and working on it some today, and i looked in the engine bay and saw something wierd looking on the right exhaust manifoldhttp://mustangunderground.com/upload...header 003.jpg

So it looks like it had been cracked or something at one point and tried to fix it up somewhat.

so now i gotta search around for some new exhaust manifold for it. Which was in my plan for it in the first place just not so soon. This may be the sound ive been notice when it is running, hard to explain what it sounds like exactly.

just get some shortys for it, they would bolt straight to the stock pipes i think

Open Long Tubes = T3H WIN

Looks like JB weld.
