Most exhaust piping is going to be measured using OD dimensions which is outer dimensions of the pipe or the outer diameter. That means if you were to purchase a three-inch pipe—let’s say like the one we have here—the outside diameter of this pipe would actually be three inches.
Is exhaust pipe measured in ID or OD?
Piping is most often measured in O.D. dimensions. It is designed to slip inside other components, most often a muffler. Mufflers and exhaust tips are most often measured in I.D.

Is it better to weld or clamp exhaust?
Welding provides you with a stronger bond than a clamp can and will last the pipe’s lifetime. The downside of welding is that you need specialized skills and tools.

Does the size of the exhaust pipe matter?
Does the size of the exhaust pipe matter? Simply put yes, the size of your exhaust pipe and mufflers makes a difference in the performance of your vehicle. Too large of an exhaust pipe size can also hinder performance, especially low RPM torque.
What is the ID of 3-inch exhaust pipe?

Does a 3-inch exhaust make a difference?
The performance you’d gain with the larger system usually isn’t worth the loss of better sound quality. However, if the engine is very built-up, and if you race it on the weekends, you may want to reap the benefits of the larger and louder 3-inch system.”Dec 1, 1998.
Does exhaust pipe size affect performance?
If you are too lazy for the details, bigger exhaust pipes do make the exhaust louder – but only by a little. Exhaust pipes are made bigger to allow better exhaust flow. This is important for increased performance and horsepower (not for the sound).
How much horsepower do you need for a 3-inch exhaust?
Our 3-inch exhaust baseline netted 527 whp at 19 psi. With the 3.5-inch exhaust, it climbed to 567 whp with a peak gain of 66 whp at 6000 rpm in fourth gear. At 29 psi, we went from a baseline of 699 to 740 whp. Peak gains here were 52 whp at 6100 rpm.
How can I weld my exhaust without a welder?
Let’s dive right in. Apply an Epoxy Bond. If the hole is small enough, you can use epoxy to seal the leak. Wrap it with Exhaust Tape. An exhaust tape is an ideal solution if you are dealing with a larger hole. Use an Exhaust Clamp. Cover the Hole with an Aluminum Patch.
Can you install a muffler without welding?
Mufflers are not an expensive part to replace, but the cost of labor can be high at a local mechanic shop. Learn now to install a replacement or performance muffler on your car without having to weld it in place or bring it to a costly muffler shop.
How long will a welded exhaust last?
Determining the Lifespan of the Exhaust System As a rough rule of thumb, however, a typical life expectancy of a premium aftermarket exhaust system should be in the neighborhood of two to three years depending on driving habits and the previously mentioned factors.
How do you find a pipe flange?
You need to find the outer diameter, the inner diameter, the number of bolt holes, bolt hole diameter, and the bolt circle diameter. Bolt circle diameter (B.C.) is one of the most important measurements to make when identifying a flange.
How are exhaust gaskets measured?
When measuring a circular gasket, think of it as a clock. Use a tape measure or ruler and measure across the gasket from the 9:00 position to the 3:00 position. Measure the inside edges for the I.D. and the outside edges for the O.D. Next, count the number of BH (Bolt Holes) around the face of the gasket.
How do you measure exhaust flange gasket?
To measure such circle measure from the center of one bolt directly across to the center of the other bolt. The Outside Diameter is the measurement of the outside of the Flange or Gasket. The Inside Diameter is the measurement of the inside of the hole of a Flange or Gasket.
Which end of muffler is Inlet?
The marking of INLET and the arrow are located on the offset end of the muffler, but the ARROW Points Toward the Center Pipe End, which means the Center Pipe End is the INLET, just like the old one.
How do I choose an exhaust tip?
The final measurement to consider when choosing your exhaust tips is length. You want your exhaust tips to be seen, but you don’t want to create a flaming-hot trip hazard for pedestrians. Make sure to choose a tip that’s long enough to vent the exhaust from under your vehicle, but short enough to keep it looking cool.
How do you connect the same size exhaust pipes?
When joining 2 exhaust pipes with the same diameter, it creates a “butt joint.” The easiest way to secure a butt joint is with a Band Clamp. To weld a butt joint, an Exhaust Welding Clamp will hold the joint while it is tacked in place. Then, remove the clamp to complete the weld.
