They replace the exhaust manifolds. Headers have a separate tube for each cylinder which makes it easier for the exhaust to flow. They are also bigger diameter so there is not as much back pressure. The easier an engine can breathe, the more horsepower it will have and the faster the car can go. It is not a huge difference, but it does help.
Borla headers are by far the best aftermarket headers available for performance cars and trucks.
I would say it all depends on your intake and exhaust system. I run mine with stock headers, nismo duel rai and 60mm invidia n1 exhaust...runs great with stock headers.. remember, just because it is aftermarket does not mean better...
Well you might try a place called Kooks headers. They specialize in custom built headers for all applications. I will tell you that this company is regarded as one of the best so be prepared so shell out the cash. Good luck with your search!
There were both small blocks and I'm going to say, yes.
I believe they should work as I think the 66 and 67 had the same body style. They will not work. If you research the TTI headers (though expensive) it will show you that the headers for the 318/340/360 are rather narrow when used for the 63-66 A-Body, when you look for the 67-72 A-Body you will see they have a much larger outward sweep thus needed much more room within the fender well. I have been beating this to death as I just pulled the 170 /6 out of my 66, and am putting in a 318. Again TTI makes one of the best headers for this vehicle, but they are around 600-700.
Open headers are essentially an open exhaust system with no mufflers or catalog converters
usually
What engine and car they were designed to fit.
you need to call summit racing and they will be able to get you the proper headers for your car.
Headers, turbos.
Headers help the engine breathe better thus better performance but the rest of the exhaust system needs to be included.
There are many online shops that sell hooker headers. Amazon.com is one of online shop that sells hooker headers for any kind of auto car. You can visit www.amazon.com
They do give more horse power
Engine specific. T he headers need to bolt onto the exhaust ports on the engine so regardless of the car the engine must be the same
The only company to sell headers made for this car is a company called Ford Power Train. Very high quality headers that are built very well. Just google the name and you will find there site.
Headers go on either side of you'r engine. They are the first part of you'r car's exhaust system. It can increase horse power, make deeper sounds, increase speed, and let's more clean air into you'r engine.
bout 10 to 25. depending on what size of motor
