What is the diameter of my exhaust pipe?

First, find the circumference of the pipe using a tailor’s measuring tape (or a piece of string you can then measure with a standard measuring tape or ruler). Then, divide the circumference by p (3.14) to get the outside diameter.

Does exhaust diameter make a difference?

Systems that are too large in diameter can actually hurt performance. As a general rule (when not running a high compression ratio, nitrous, and/or a blower), switching to a performance exhaust system that is 1/4- to 1/2-inch larger than stock will provide you with the best horsepower increase.

Can exhaust be too big?

Yes, it is possible for exhaust piping to be too large. When the pipe diameter increases, the exhaust gas velocity decreases and can be detrimental to engine performance. As you are aware, another drawback of tubing that is too large, is increased noise.

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 much horsepower can 2.5 inch exhaust support?

Registered. Theoretically 500hp for 2.5″ exhaust.

What size exhaust tip should I get?

Inlet Size The inlet size of your exhaust tip must match the diameter of your existing tailpipe for a proper fit. For example, if your tailpipe has a 3″ diameter, choose an inlet diameter of 3″. Remember, your tailpipe may already have a tip, so be sure to measure the tailpipe, not the old tip.

Is 2.5 or 3 inch exhaust better?

yes 3″ probably better, but might be hard to run all the way to the back next to the tank, if your using the smaller TTi headers i don’t think the 3″ would give much more HP, you could also go 3″ to the muffler and 2.5″ out the back.

Is 3 inch exhaust too big?

The general rule of thumb for exhaust systems is, as we said 3-3.5in for 250-350whp, above that 4″ exhaust is the right size, but that’s about as big as you want to go, even at the 400whp-500whp level.

Is 4 inch exhaust too big?

This means that an extremely large exhaust pipe will actually cause SLOWER exhaust flow, and decreased performance. The general rule of thumb for exhaust systems is, as we said 3-3.5in for 250-350whp, above that 4″ exhaust is the right size, but that’s about as big as you want to go, even at the 400whp-500whp level.
