What makes a good exhaust sound?
High-frequency waves travel well through dense, pressurized air; low-pressure soundwaves continue to fare well when system pressure drops. That’s why high-performance, high-flow exhaust systems naturally sound lower than their lower-flowing, higher-pressure counterparts.
How can I improve my exhaust scavenging?
Smaller diameter pipes near the engine increase the velocity of the pressure pulse and thereby increasing the effect of scavenging from a longer and lower pressure after the pulse. Continuing down the exhaust tubes the next experiments were taken at the Y-pipe primaries.
Where Can I drill a hole in my exhaust to make it louder?
Set the drill bit against the bottom of the muffler. It really doesn’t matter where you drill the hole, but if you want to make sure that moisture does not collect inside the muffler, drill on the bottom of the muffler.
Can a exhaust tip change the sound?
The shape and width of the exhaust tip can slightly change the sound to be either more throaty (larger tips) or raspy (smaller tips). Double-walled muffler tips tend to add a full-bodied sound. On their own, though, muffler tips will have a minimal effect on exhaust sound.
Can you make a 4 cylinder sound good?
Rather you can choose the classic 4 cylinders with a little update by adding a quality muffler to reduce the vibration and get smooth idle and better sound.
Can an 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.
How much HP can 2.5 exhaust support?
Registered. Theoretically 500hp for 2.5″ exhaust.
How big should a single exhaust pipe be?
Buz – The size of your exhaust system pipes should be matched to the power of your engine. So, if you have an engine that generates less than 100hp, the proper single exhaust tube size is 1 3/4″ .
How to calculate the volume of exhaust pipe?
Easy Way To Estimate: Your intake system needs to flow 1.5 CFM per engine horsepower, and your exhaust system needs to flow 2.2 CFM per engine horsepower. Good Way To Estimate: Take engine RPM x engine displacement, then divide by two. This is the intake volume.
What should I look for in a performance exhaust system?
One of the first concerns when building or buying a performance exhaust is sizing. The tube length and diameter directly affect the way in which the final system influences the engine and exhaust note, as in all racing applications form should follow function — and be informed by it.
Why do you need to increase the exhaust diameter?
The whole idea is to increase your exhaust diameter as the amount of exhaust your engine creates increases. This reduces restriction and allows for more flow. If you have modified your engine, you’ll need to modify the exhaust as well to allow for more airflow.
