Are mufflers measured ID or OD?
Mufflers and exhaust tips are most often measured in I.D. dimensions. A lap joint is the intersection where the pipe slips inside another exhaust component. A butt joint occurs when two sections of pipe can’t slip inside the other because they have the same O.D.
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).
Which is better 4 or 5 inch exhaust?
For most trucks, the difference in these exhaust systems comes down to how it sounds. So, no, you’re not getting much more flow with a 5” because your 3” or 4” downpipe is restricting your entire exhaust system. That being said, that doesn’t mean there isn’t a difference in these systems.

Does straight pipe hurt your engine?
The straight pipe exhaust system does not hurt the engine in any way. Since the system has no muffler, it produces pure and raw sounds from the engine. If you install the straight pipe exhaust system, it helps to improve the sound of your engine.
Is it bad to straight pipe your truck?
a race car style exhaust system is a bad upgrade for a street vehicle. A straight pipe, for example, can cause exhaust gas velocity to increase. This will likely reduce engine performance below 2,000 or 2,500 RPM, making your vehicle a little slower to launch from a stoplight.
Can I put a straight pipe in place of my catalytic converter?
Before replacing your expensive catalytic converter, make sure it is the culprit by replacing it temporarily with a straight pipe, sometimes called a test pipe. If your car runs properly with the test pipe in place, your catalytic converter will need to be replaced soon.
Do you lose torque with straight pipes?
No it won’t. That’s a myth. Changes in the a/f and loss of exhaust velocity will affect torque.
