Are all exhaust pipes the same size?

Proper exhaust-pipe size is a function of both engine output and displacement. The higher the engine’s output, the larger the pipes should be. Likewise, larger engine displacements call for bigger pipes. The accompanying exhaust system size guidelines are compiled from Flowmaster Mufflers and RoadkillCustoms.com data.

Is exhaust pipe measured ID or OD?

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.

What happens if your exhaust is too big?

Since there’s more volume for the exhaust gas to travel through, the gas has plenty of time to cool off. And that cooler air is heavier and so your engine has to work harder to push it through the system. This means that an extremely large exhaust pipe will actually cause SLOWER exhaust flow, and decreased performance.

Is a bigger exhaust pipe better?

The more exhaust your engine produces, the less the gas expands. The less it expands, the less it cools, and the faster it goes. So, basically, bigger exhaust means more power at high RPMs, and less power at low RPMs.

Is 3 inch exhaust too big?
