hey guys

thinking of getting these:

dont know much about exhaust systems. wanted to know if installing these are newb friendly.

all i know is that headers replace the exhaust manifold.
what i want to know is:
1. do i need to remove engine to install
2. will they fit with a stock exhaust on a 67 coupe.
3. if i have to remove engine hw hard is that to do.

 

Couple of things to consider. Thickness of the tubing and flange. The flange, the flat part that bolts to the motor, needs to be as thick and flat as possible for the best seal. Thin flanges tend to warp from heat/cold and you'll have issues with blowing header gaskets.... Additionally, you need to include the cost of modifying your existing exhaust, it has to be cut, and the new collectors attached, and hopefully a crossover pipe added. If you do it yourself, great, but a muffler shop will cost you another several dollars. Good luck. Enjoy.

 

Pay the money to get a good set of headers, it will save you money and headaches in the long run.

 

For a mildly modified engine I would buy HiPo exhaust manifolds.
Easy install.
Leak free.
Last forever.
DIY ceramic coatable.

If must have headers I would only use thick flange ceramic coated stainless steel. Otherwise, always chasing leaks and rust.

 

so i need to remove engine?

 

LOL..."So what you are all saying about the flanges is that I have to remove the engine?"

No...engine stays in. Headers go in from underneath car

 

Headers can be very hard to install depending on engine and accessories.

Miles of leaky header horror stories; look for best quality not best price.

Local Hot Rod muffler shop will not install headers.

Do you have a 289? Auto trans? Z-bar? Just triple check everything.

I've had three sets of headers.

All advertised to fit my application.

I had to modify every set.

On my 67 I can drop shorty headers in from the top just like exhaust manifold; nice.

 

I heard shorties might have clearence issues, as in their really close to the ground.
I have a 67 289 auto trans whole thing is stock for now.....

Btw
I love mobile view

 

Clearance issues are about who makes them, not what type. Some manufacturers make LT's that fit perfectly, others make shorties that don't even fit at all in some cases.

 

Guess you know a stock 289 will have little benefit w/ headers.
