How do you bend exhaust headers?
If you prefer to try to bend the one you have I would bolt the flange down to something solid using the holes in the flange. Find a long round steel tube or rod to fit perfectly outside or inside of the header tube a few inches and give it a gentle nudge in the right direction.
What is the formula for bending pipe?
π(2r) or πD. π (pi) = 3.1416. For example, if your die creates a 2.2” radius, and you need to create a 35° bend, your calculations would look something like this: to calculate one degree of bend. 3.1416(2x2.2) = 13.823/360 = 0.0384.

How to bend a custom exhaust pipe?
Bending the exhaust tube yourself is a delicate process but entirely feasible with the right equipment. Fill the pipe with sand to prevent crimping when you bend it. Attach a thick walled squash pipe to provide a gripping point for the vise or clamp.
How to flatten exhaust pipe?
Take the thin metal exhaust pipe and flatten one end by striking it with a hammer or squashing it in a vice grip.
How to bend squash pipe?
For best results, preheat the tube in the oven. Grip the squash pipe in the vise and use a torch to heat it until it glows red. Work slowly while bending the pipe. Pull it as you bend it to prevent kinks from forming. Check against your patterns as you work. If you are bending a pipe in more than one location, allow it to cool completely between bends.
How to bend exhaust pipe?

Why bend exhaust pipes yourself?
An inexpensive alternative to buying pre-bent pipes, bending exhaust pipes yourself allows you to replace a leaking or rusted pipe quickly and efficiently. Bending your own exhaust pipes ensures the best fit possible, because you adjust the bends as required, creating the custom fit needed. Improper bending of exhaust pipes, especially when making tighter bends, can ruin the pipe by causing it to crease at the point of the bend. There are two ways to prevent pipe creasing, mandrel bending and filled-pipe bending. Filled-pipe bending is easiest with shorter pipes.
How to prevent pipe creasing?
There are two ways to prevent pipe creasing, mandrel bending and filled-pipe bending. Filled-pipe bending is easiest with shorter pipes.
How to stop a pipe from collapsing?
Pack the pipe tightly with sand and cap both ends of the pipe. There must be enough pressure in the pipe to prevent the walls of the pipe from collapsing when you make the bend. Put the welding gloves on.
How to measure a 90 degree bend?
On 90-degree bends, measure this as the distance from the end of the previous pipe to where you want the far wall of the pipe after the bend. For smaller bends, this is where you want the change in direction to begin. Add two to three inches for pipe connection overlap where ...
How to optimize exhaust gas?
By "tuning" the exhaust gas path i.e. varying the diameter (and therefore volume) and length/position of various restrictions (e.g. catalytic converter, pre-muffler, muffler, etc.), the engineer can optimize the extraction effect for specific RPMs. For example, to maximize power output, the frequency of exhaust waves might be tuned to be optimal at more or less the peak output RPM. To maximize drivability, the frequency might be tuned to be optimal at more frequently used RPMs.
What kind of saw to use for exhaust pipe?
If you are fabricating an exhaust system and have the pipe in your hand, an abrasive cut-off chop saw is ideal. In the car, a saws-all or abrasive wheel on an angle grinder works well. I have used an air powered hack saw in a few cases. A bit messy, an oxyacetalene torch works if you are careful, requires practice.
What is the goal of pulses in the exhaust gas stream?
Besides the goal of "get spent combustion by-products out of cylinder (s) as quickly as possible" described in JW Briggs' answer, another goal is to take advantage of pulses or waves in the exhaust gas stream to aid in extraction of exhaust gas from cylinder (s) (since street legal production vehicles must have restrictions in its exhaust path in the form of emission control and sound mitigation anyway).
How do waves occur in exhaust gas?
Waves occurs in exhaust gas when the exhaust gas stream encounters restrictions in the exhaust path, the same way surface waves in a container of water bounces back from the container's walls. A wave would bounce back from a restriction in the exhaust gas path until it arrives back at the exhaust valve whereupon it would bounce back down the exhaust gas path and so on. These waves would diminish over time in frequency and amplitude.
What causes waves in exhaust gas?
Waves occurs in exhaust gas when the exhaust gas stream encounters restrictions in the exhaust path, the same way surface waves in a container of water bounces back from the container's walls. A

The exhaust systems are set up on the right side to help prevent the heat from going up in the passenger cabin. They have studied drivers' habits and vehicles usually have a single occupant (driver) in the vehicle about 68 % of the time.
Step 1: Pack Your Pipe
The first thing to do is to plug one end of the pipe. I used a small carriage bolt that fit snugly in the end. The next step is to fill the pipe with sand. I used beach sand. The sand should be nice and compact to stop the pipe from buckling.
Step 2: Bend!
Clamp one end to a form. Here I used a wine barrel planter and then added a rounded block (that just happened to be in my workshop) to get a tighter radius. You will likely need a lot of leverage to bend the pipe. This piece was 4 feet long and it took some muscle to get the bend.
Step 3: Finish It Up
Cut the deformed end off. Clean out the sand. I used a piece of string with a rag on the end to get all the sand out. The picture below shows the slight dimple in the center of the bend.
