Just had my 351 c. m code rebuilt , with upgraded cam, punched out .030. I torn between going with stock exhaust or headers. Your in put apreciated.
I have heard good reviews about the Pypes exhaust system so I decided to go with those. Not installed yet but they are sitting in the garage and the quality looks really good. I'll comment soon when I try to install them.I have been thinking about this as well. I'm a ways off but was wondering if the shorties buy you much. Also, I'm worried about the whole system being compatible. I don't know what picking headers, pipes, and muffler from three different sources does vs. A complete tuned system. I would love to hear some comments on this.
I believe that Travis (aka Doug the Dog) has a source for them.Thanks for the input guys. I like the idea of using shortys but does not look like they are available for 351 4v Mach 1
They are available

I'd opt for ceramic coating as it keeps some heat out of the engine compartment.
I agree with almost everything that has been said with the one exception being the loss of torque-it's a myth in my opinion and probably caused by a failure to tune engines and make appropriate jetting changes to a cars carburetor after header installation.
this is true- huge primary pipes can reduce effective scavenging especially when the cam isn't matched to them.You have to go too big on primary pipe diameter for the torque loss to occur. For example, 1 and 7/8 primary pipe on a Boss 302. One guess as to how I know this. Chuck
