Short OR Long headers
every one on this site has told me to go with long headers, but when i went to the local speed shop the dude told me that the Trans AM and Mustang are made to have short headers. Keep in mind this will be my frist mod so i wanna make the exhust improve my low end not my top.

Shorties really aren't worth anything over stock. There are also mid length headers available, which will make a little power over stock. Long tubes will make the most power though.

Who's to say what type of part was made for what car?
That guy's an idiot. Go with longtubes and don't worry about it.

Your stock cats won't work with LTs, but you can put high flow aftermarkets on there to keep it legal and pass emissions.

Go with Long Tubes, you won't regret it.
Shorties aren't worth wasting your time, the stock manifolds are practically shorties.

Go with long tubes you will see a lot more torque than shorty or mid headers. You can install 02 simulators if you dont want to put cats back on your car, so you can pass smog

Generally both, as they have less backpressure than manifolds. You'll notice the gains in the upper RPMs. You really won't feel much of a gain in the lower RPMs.
Here's a pretty decent header article. It doesn't really explain what the headers will do for you, but show variances in power produced by various header sizes: http://www.carcraft.com/techarticles...e_header_test/

All you guys on the other side of the country are lucky bastards!
Here in CA, emissions are a thorn in our sides. The last 2 times I've gone for smog check, one of the first thing those guys do is look under my car (2 C if I've replaced the headers with long-tubes.) What a bunch of Haters!!

That sucks for you. I dont even have to smog my car. You got to love living by a small town.

In Kentucky, they don't care what you do with your exhaust. I passed an out of state title transfer inspection on a '79 Z28 with headers and turndowns. Probably 3/4 of the cars here would fail an emissions test.

Alright, alright, all you haters!
Yeah, I know some guys around here are able to find someone who'll take cash to look the other way, but I haven't found one yet. At least, that's the ONLY mod I can't have. Would be nice though.
