A high performance aftermarket exhaust manifold can deliver 

a performance increase over a stock OEM exhaust manifold. 

Separating Exhaust Gas Pulses 

All V8 engines have a firing order that fires two cylinders within 90 degrees of each other 

on the same bank of cylinders. With a firing order of 1-8-4-3-6-5-7-2, we have #8 and #4 

firing on the starboard side of the engine within 90 degrees of crankshaft rotation. On the 

port side, we have #5 and #7 firing within 90 degrees of crankshaft rotation of each other. 

Of course, this also means that the exhaust gases for these cylinders immediately 

discharge into the exhaust manifold one after the other. 

At this point, when the two cylinders fill the manifold in immediate succession, the 

exhaust manifold becomes overwhelmed with exhaust gases, creating excessive back 

pressure. In fact, excessive backpressure from an overwhelmed exhaust system will not 

only keep spent gases from leaving the cylinder head exhaust port, but in certain ports, 

exhaust gases from adjacent cylinders may find their way back in. 

The solution is to isolate each exhaust gas pulse for as long as possible in the exhaust 

manifold. There are aftermarket manifold manufacturers that go to great lengths to isolate 

each exhaust pulse the full length of the manifold, and there are some that barely address 

the problem at all. Choosing a high performance manifold that isolates each runner is the 

key to building horsepower with the exhaust system.

Cross Section 

If properly designed, it can achieve this by two ways: 

Separating Exhaust Gas Pulses and Lowering Back Pressure. 

Separating Exhaust Gas Pulses Continued... 

Because the starboard side of the engine fires #4 and #8 in succession, there is a 

cylinder (#6) separating the two. Dividing this manifold into two different sections by 

grouping #2 and #4 in the front half of the manifold and #6 and #8 into the back half of 

the manifold works relatively well in isolating the #4 and #8 cylinders. On the port side of the 

engine we have a problem: The #5 and #7 cylinders that fire in succession are next to each 

other. 

Dividing the port manifold into a front half and a back half groups cylinders #1 and #3 

together (which is okay), but groups #5 and #7 together (which is definitely not okay). 

This is exactly what we are trying to prevent! The correct way to build the port side manifold 

is to isolate the exhaust gases from cylinders #5 and #7 all the way to the manifold exit. 

Lowering Back Pressure 

Lowering back pressure in the exhaust manifold is a combination of isolating the 

exhaust pulses as discussed in the previous section, and simply making the exhaust 

system larger. Some techniques for lowering back pressure include: large passages in the 

exhaust manifolds, a large exit hole out of the manifold, a large exhaust pipe and large 

radius curves in the pipe wherever the exhaust gases have to change direction.”

All V8 engines have a firing order that fires two cylinders within 90 degrees of each other

firing on the starboard side of the engine within 90 degrees of crankshaft rotation of each

discharges into the exhaust manifold one after the other. It is at this point, when the two 

cylinders fill the manifold in immediate succession, that the exhaust manifold becomes 

overwhelmed with exhaust gases, creating excessive back pressure. In fact, these two 

cylinders on each bank firing in succession, not only create excessive back pressure in the 

manifold, but all the way down the exhaust pipe. Excessive back pressure from an overwhelmed 

exhaust system will not only keep spent gases from leaving the cylinder head 

exhaust port, but in certain ports, exhaust gases from adjacent cylinders may find their way back in. 

The solution is to isolate each exhaust gas pulse as much as possible for as long as 

possible in the exhaust manifold. There are aftermarket manifold manufacturers that go to 

great lengths to isolate each exhaust pulse the full length of the manifold and there are 

some that barely address the problem at all. 

Divided Exhaust Manifolds 

Because the starboard side of the engine fires cylinders 4 & 8 in succession, there is a 

cylinder (#6) separating the two. Dividing this manifold into two different sections by grouping 

cylinder #2 and #4 in the front half of the manifold, and #6 and #8 into the back half of 

the manifold with a divider, works relatively well in isolating cylinders #4 and #8. On the port 

side of the engine, we have a problem. The cylinders that fire in succession, 5&7, are next 

to each other. Dividing the port manifold into a front half and back half groups cylinder 1&3 

together (which is okay) but also groups cylinder 5&7 together (definitely not okay). This is 

exactly what we are trying to prevent. The correct way to build the port side manifold is to 

isolate the exhaust gases from cylinders 5&7 all the way to the manifold exit. This can not 

be done with a simple divider in the middle of the manifold. 

Lowering Back Pressure 

Lowering back pressure in the exhaust manifold is a combination of 

isolating the exhaust pulses as discussed in the previous paragraph 

and simply making the exhaust system larger. Large passages 

in the exhaust manifolds, a large exit hole out of the manifold, a 

large exhaust pipe and large radius curves in the pipe wherever 

the exhaust gases have to change direction are the secrets to 

lowering back pressure.”
