What size exhaust pipe should I use?
What Size Exhaust Pipe Should I Use? The quick and easy way to choose what diameter pipe you will need from the headers to the mufflers is to go back to the old rule of thumb, that for every 100 horsepower, 1 inch of total pipe diameter is needed across the system. For example, a 500 horsepower engine would require a 5-inch exhaust pipe (split ...

What size pipe is our exhaust?
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.
What gauge is exhaust tubing?
most headers are 18 gauge steel , most exhaust is 16 gauge or thicker , same material unless you got stainless headers or tails .Aug 2, 2013
What kind of tubing is used for exhaust?
Stainless steel is the most expensive choice. It is also more difficult to bend and weld. There are different grades of stainless steel. 409 and 304 are the most popular grades used in exhaust parts.Apr 18, 2017
Can you use aluminum for exhaust?
There are many positives to using an exhaust system crafted from T6061 aluminum where possible instead of a stainless steel variant. T6061 aluminum has high corrosion resistance due to its alloy makeup, which includes other elements like magnesium.Aug 29, 2016
What metal is used for exhaust?
Abstract: The most common types of steel used in exhaust systems include ferritic and austenitic stainless steels, as well as various grades of aluminized steels.
How many CFM per square inch of exhaust pipe?
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:
How many pipes does a 400 HP exhaust need?
The table above is probably over-estimating pipe size, but you can see that a 400 hp vehicle with a dual exhaust system only needs 2 1/4 – 2 1/2 inch pipes. Anything larger is overkill.
How to calculate the volume of air an engine takes in?
Conservation of mass, right? 2) To calculate the volume of air the engine takes in, we multiply the displacement of the engine by the engine RPM and then divide by two (it takes two full revolutions for the engine to exhaust it’s entire air volume).
Is a factory exhaust pipe diameter good?
However, if you find yourself getting stuck (or bored) with the info below, here are the key take-aways: 1. The factory exhaust pipe diameter is usually a good choice for most vehicles. 2. The muffler manufacturers are doing all the math for us – no need to reinvent the wheel. If they say it will work for your vehicle, ...
What is the most common pipe size for a turbo manifold?
The most common pipe size wall thicknesses, or schedules, when building a turbo manifold are Schedules 5, 10, and 40. Although there are many other possible schedules, depending on the nominal size and type of material, these three are the most common when talking about turbo manifolds. The benefits of choosing one over ...
What material is used for intercooler piping?
If you're building your own intercooler piping was always suggest tube size material ( mandrel bends, straight tube, v-band assemblies, dual seal clamps, or VanJen assemblies, etc.). Aluminum is by far the most common choice, yet some fabricators choose to use stainless steel material for their intercooler piping.
What is the most common gauge for a 4.000" diameter?
There are many other gauges available for the listed diameters; however, 16 gauge is by far the most common size for diameters 3.500" and smaller. For applications where 4.000" diameter material is used both 14 gauge and 16 gauge are common.
Can you fabricate a turbo manifold?
Aside from the technical challenges of choosing your desired style of manifold, brand of turbo and size, and wastegate placement, the choice between using pipe size or tube size material for your turbo manifold can be quite confusing. What about fabricating your own exhaust system, intercooler piping, or dump tube — how do you know which type of material to choose?
Is pipe size more robust than tube size?
Pipe size material, due to its thickness, is far more robust than tube size material, especially when you hang a 20-40 pound turbo off of the side, heat the material up to incredibly high temperatures, and then add vibration and stress into the equation. Also, most aftermarket head flanges meant for turbo applications are optimized for ...
