6.7 Cummins Stock Exhaust Size

The stock exhaust size for the 6.7 Cummins is 3″ diameter. This is the factory size that comes on the truck from the factory.

The 6.7 Cummins is a powerful engine, and one of the most popular choices for diesel trucks. It’s known for its reliability and towing power, but what about its exhaust size? Just like any other engine, the 6.7 Cummins has a specific exhaust size that it needs to operate correctly.

The stock exhaust size for this engine is 3″ in diameter. This may seem small, but it’s actually the perfect size for this engine. Any larger and the engine would lose some of its power, and any smaller and it wouldn’t be able to breathe properly.

3″ is the standard exhaust size for most diesels, so if you’re looking to replace your 6.7 Cummins’ exhaust system, you don’t need to worry about finding a custom option – just find a 3″ system and you’ll be all set!

6.7 Stock Exhaust Size

If you own a vehicle with a 6.7L engine, then you know that finding the right size exhaust can be difficult. Most aftermarket exhaust systems are designed for 5.7L or 6.1L engines, which means they might not fit your 6.7L engine properly. In addition, many 6.7L engines come with a factory-installed muffler delete, which can make finding the right size exhaust even more difficult.

Fortunately, there are a few companies that offer 6.7L-specific exhausts. These kits usually include everything you need to install the system, including all necessary hardware and instructions. The best part is that these kits are designed to fit your vehicle perfectly, so you won’t have to worry about any compatibility issues.

6.7 Cummins Stock Downpipe Size

If you’re in the market for a Cummins downpipe, you may be wondering what size to go with. The stock downpipe on the 6.7L Cummins is 3″ in diameter, but there are a few aftermarket options that are available in both 3″ and 4″ diameters. So, which size should you choose?

3″ vs 4″ Downpipes There are a few things to consider when deciding between a 3″ and 4″ downpipe. The first is power potential.

A larger diameter pipe will flow more air, which can lead to increased power output. If you’re planning on making some serious power mods to your Cummins, then a 4″ pipe may be the way to go. However, if you’re just looking for a little bit of extra power, then a 3″ pipe should suffice. The second thing to consider is exhaust backpressure.

Too much backpressure can rob your engine of power and efficiency. A larger diameter pipe will typically create less backpressure than a smaller diameter pipe due to the fact that it can flow more air. So, if you’re concerned about backpressure, then again, a 4″ pipe may be the better option.

The last thing to think about is cost. Larger diameter pipes tend to cost more than smaller ones simply because they require more material to construct them.

The 5.9 Cummins is a great engine, and one of the things that makes it so great is the fact that it comes with a stock exhaust system that is the perfect size for most applications. This means that you won’t have to worry about upgrading your exhaust system right away, and you can save some money in the process. However, there are still some people who want to upgrade their exhaust system anyway, and if you’re one of those people then you’ll need to know what size exhaust pipe you need.

The stock 5.9 Cummins exhaust pipe is 3 inches in diameter, but there are also 4 inch pipes available as well. If you’re looking for more power then you’ll want to go with the 4 inch pipes, but if you’re just looking for a little bit more sound then the 3 inch pipes will do just fine. Either way, make sure you get the correct size pipes so that your upgrade will be successful.

What Size Exhaust is on a 2022 Ram 3500?

When it comes to the 2022 Ram 3500, there are two different engine options that you can choose from.

Both of these engines offer different exhaust sizes, so let’s take a look at each one in more detail.

The 6.4L V8 HEMI® with MDS offers an exhaust size of 3″ diameter while the 6.7L I6 Cummins® Turbo Diesel offers an exhaust size of 4″ diameter. So, if you’re looking for more power and performance from your Ram 3500, then opting for the diesel engine is the way to go. However, both engines offer plenty of power and torque, so it really comes down to personal preference in the end.

What Size is a Stock 6.7 Cummins Turbo?

The Cummins 6.7L turbo is a variable geometry turbocharger (VGT), also known as a compound turbo. The VGT has two smaller turbos in a single housing, with the exhaust from the first turbo spinning the second turbine. This design allows for quick spool-up of the turbos, resulting in more power and torque at lower engine speeds.

The VGT is available in three sizes: small (S), medium (M), and large (L). The S size turbo is designed for engines up to 1,100 horsepower (hp) and 2,000 lb-ft of torque (lb-ft). The M size turbo is designed for engines up to 1,300 hp and 2,500 lb-ft of torque.

The L size turbo is designed for engines up to 1,600 hp and 3,000 lb-ft of torque.

How Much Boost Can a Stock 6.7 Cummins Handle?

The 6.7L Cummins is built tough from the factory to handle a lot of power and abuse, but there are still many people out there wondering just how much boost this motor can really handle. The simple answer is: it depends. We have seen stock 6.7L motors hold up to 35 psi of boost without any issues, but it really starts becoming a crapshoot after that point.

Some motors will hold more power and some will start having issues, so it really varies from truck to truck. If you’re planning on running a lot of boost on your 6.7L Cummins, we would recommend doing some upgrades first to help ensure that your motor can handle the extra power. Upgrading the pistons, rods, and bearings is always a good idea when looking to make big power as they are typically the first components to fail under high stress situations.

In addition, upgrading the head gaskets and oil cooler are also recommended as they can help prevent leaks and overheating respectively.

Conclusion

The take away from this blog post is that the 6.7 Cummins stock exhaust size is 3 inch diameter. This is a good thing to know if you are planning on upgrading your exhaust system.
