What does a larger diameter exhaust do?
Bigger exhaust pipe makes sure exhaust gases leave the combustion chamber quickly. They create lower air pressure in the exhaust system and force the exhaust gases to leave (air particles always travel from high pressure area to lower).
How do you size a muffler?
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).
Can a muffler be too small?
The term refers to the atmosphere which pushes down on your exhaust system. And back pressure generally has a very negative effect on your engine’s power output. And if the exhaust pipe diameter is too small and it generates too much back pressure, these exhaust gases will be heavily restricted from exiting the engine.
Do turbos like back pressure?
If you are too lazy to read – Back pressure is not good for turbo (or for anything else). With back pressure, exhaust gases cannot easily flow in the exhaust system. Which means they will spool the turbo with reduced force – resulting in power loss and more turbo lag.

How much CFM does a exhaust pipe use?
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: NOTE: These numbers are just estimates.
What does the Harman p38 circuit board upgrade kit do?
