For 4-2-1 use:# (2,5,) (3,4,) (6,7,8,)
Notes 1
Speaking of 4-2-1 extractors, this is the WRONG WAY to do it on a four cylinder engine! A 4-2-1 system must have cylinders #1 & #4 joined up, and #2 & #3 joined up, then further down those two pipes join into one.
This is because four cylinder engines have a 180° crank, whereas virutally all V-8's have a 90° crank (the angle between the crankpins) and so the order in which the exhaust pulses come down the pipes is different.
Notes 2
A reduction in primary pipe Diameter of 1/8 of an inchwill move the torque peak down by 650-800 RPM.Conversely an increase in diameter of the header will raisethe engine speed at which max torque occurs,by approx the same RPM,for each1/8 of increase.
Adding length to the primary pipe will increase low speed and mid-range power,with corresponding reduction in power at max RPM.
Shorter primaries give an increase in high speed power,at the expense of reduction in the midrange.However,there will be little change in peak torque orthe engine speed at which it occurs.

For road , you'll be best off with a 4-2-1 system on a four cylinder engine.
For high performance & race use, the only way to go is a 4-1 system.
The 4-2-1 system gives good all-round power, with no special power peaks or dips, while a 4-1 system give the best power at higher revs - At the expense of low end power.

The tables below are basic references to help guide you to the exhaust-pipe size needed to balance the prevention of excessive back-pressure while maintaining adequate exhaust-gas velocity.
Editor’s Note: The easy to read tube size charts replace our original exhaust diameter calculator for ease of use.

Quick Exhaust System Math
Tuneskit video cutter for mac download free. Easy Way To Estimate: Your intake system needs to flow 1.5 CFM per engine horsepower, and your exhaust system needs to flow 2.2 CFM per engine horsepower.
Good Way To Estimate: Take engine RPM x engine displacement, then divide by two. This is the intake volume. Use this same volume of air for the exhaust system, but then correct for thermal expansion (you need to know exhaust temps to figure things out).
Exhaust Pipe Size Estimate: A good section of straight pipe will flow about 115 CFM per square inch of area. Here’s a quick table that shows how many CFM each common pipe size will flow, as well as the estimated max horsepower for each pipe size:
