With the presence of this unit, you will be able to provide a rather rich and mellow exhaust note. Not only that, but the vehicle will increase mileage by roughly two miles.

Sinister Diesel Cold Air Intake for 2013+ Dodge/Ram Cummins 6.7L


  • Cotton Filter Media that is Oversized and Reusable.
  • Throttle response and turbo spool-up have been significantly improved.
  • It’s ideal for everyday driving, towing, or race days.
  • When paired with a sinister diesel exhaust or tuner, it’s unstoppable.


  • It is overpriced. For the price, a cleaning and oiling package should be included.

Intakes from Sinister Diesel are developed, manufactured, and produced in-house for industry-leading performance and longevity. For maximum performance and strength, we use CNC mandrel-bent aluminum tubing in all of our intakes. This package includes silicone couplers that are significantly more reliable than OEM materials, allowing you to rely on outstanding performance when it counts.

All of the kits include all of the essential installation gear, allowing them to be installed using standard tools and with no experience. For a long-lasting, eye-catching appearance, Sinister Diesel intakes are polished and powder coated in our unique Sinister Blue.

Technically, aluminum would be more susceptible to heat since it is metal, but it is thin-walled tubing that would dissipate the heat much faster when air moves through it. The problem with a plastic intake is that, while it takes the same amount of time to heat up, it takes far longer to dissipate the heat buildup, also known as heat soak.

We could easily outsource our intakes like most other firms, but we choose to spend more time and work making these in-house using our own welders and materials out of far better material. We’ve been testing and running these for a while now, and they’ve outperformed every other intake we’ve tried.

  • Converts a dual-tip exhaust system to a quad-tip system.
  • The track’s exhaust tone is improved by removing the rear muffler.
  • It’s 8 pounds lighter than the standard exhaust.


  • It’s possible that the manufacturer’s warranty isn’t valid.

Chevy opted to lessen the pain on the driver’s budget at the petrol pump with the debut of the 6th generation of the classic Camaro, while still giving the majority of the muscle car experience. While the LTG has enough grunt to make you smile, it still lacks that traditional muscle car sound.

A short look beneath the rear bumper reveals GM’s usual suitcase-style muffler system, which not only reduces the volume of the exhaust noise but also adds weight. With the quad-tip Race Axleback Performance Exhaust system from Mishimoto, you can cut weight and increase the volume on your 2.0T Camaro.

Ditch the suitcase in favor of 3-inch diameter, 304 stainless steel muffler deletion piping, which will save you 8 pounds while giving your Camaro the turbocharged, sporty sound it deserves. This axle-back system also includes quad4″ double-wall tips in a polished or black finish to fill out the cutouts in your rear valance, as well as the Mishimoto Lifetime Warranty.

Buying Guide – Which features should you look for in the best exhaust for 6.7 Cummins?

If you’re looking for the best exhaust system money can buy, we recommend spending a few minutes reading through this page. Because many exhaust systems are specifically developed for a certain requirement, such as towing, hauling, or racing, picking any high-end exhaust system may not be the ideal method for you.

You could think that all of the exhaust systems on our list are good choices, and you’d be right. Having said that, if you examine the price and other variables that will help you make your decision, just one of the exhaust systems can be the ideal choice for you.

The installation procedure is as follows:

With each product review, you’ll note that we’ve included whether the installation is simple or difficult. This is because the exhaust system for your 6.7 Cummins should be ordered with installation in mind. Some exhaust systems are easier to install than others, and some companies may even advise you to hire a professional to do it for you.

Needless to say, we like the exhaust systems that are simple to install. This is due to the fact that they may be completed in under an hour and save you money. Hiring a professional to come to your home and install an exhaust system on your vehicle can be expensive, and it may not be a cost you’re willing to pay – especially if you know you could have done it yourself.

Noise & Sound:

There are several types of people that are looking for an exhaust system. We can’t say we blame them if they want a loud and strong exhaust system. Having a huge pickup truck is remarkable in and of itself, but having a low and scary growl to go with it is the cherry on top.

That’s why sound is so crucial in an exhaust system, and we’ve included it in all of our assessments on this page. We only chose products that have a well-balanced sound, although there will be slight changes in the level of that sound. Some exhaust systems are specifically built to produce an outstanding sound, so no one will ever forget that you own this pickup truck!

Others have a nice sound, but they’re also understated. This would be a better option if you don’t want to wake up the neighbors, or if you’re just a classy and subtle type of guy.


Durability, like price, is another issue that makes you reconsider your relationship with your truck! Higher durability nearly always comes at a higher cost, so consider how long you’re willing to stick with this vehicle. If you plan on upgrading to another pickup vehicle shortly, it’s not a good idea to invest in a high-end, long-lasting exhaust system.

Durability, on the other hand, is always a plus. You don’t want to invest valuable time and money on the best exhaust for 6.7 Cummins system on the market only to have it rusted in a few years. We recommend that you look for materials that are anti-corrosive or have an anti-corrosion treatment because rust and corrosion are some of the main killers of a well-operating exhaust system.


When it comes to choosing the best exhaust system for your 6.7 Cummins, this is arguably the most crucial consideration. While it’s easy to state that the greatest exhaust system is a high-end exhaust system, this may not be the best advice for everyone.

If you’ve already spent a lot of money on your truck’s accessories, you might be hesitant to spend more money on an exhaust system. You should also consider your level of dedication to your truck.

If you plan on spending another decade or so with the love of your life (yeah, we’re still talking about your truck), investing in the greatest exhaust system makes sense because you’ll need the durability.

FAQs (Exhaust For 6.7 Cummins)

Is an exhaust system going to increase my engine’s horsepower and torque?

The horsepower and torque of your 6.7 Cummins can both be affected by an exhaust system. You must realize the consequences of a blocked exhaust system on your engine. There can be a lot of trapped air and gas in an inefficient exhaust system due to too many bends in the exhaust pipes or the pipes being too narrow.

Getting the correct exhaust system will allow your vehicle to breathe and allow your engine to perform at its best, increasing horsepower and torque.

What comes out of a 6.7 Cummins exhaust system?

This is a fantastic query. Exhaust systems eject a large number of pollutants, which is why they are designed to do so as quickly and efficiently as possible. Typical impurities found in the exhaust pipe under your vehicle include carbon monoxide, carbon dioxide, and even a significant amount of water vapor.

Additionally, there is a significant amount of nitrogen and sulfur dioxide present.

Is it true that exhaust brakes are hazardous for diesel engines?

Please keep in mind that the exhausts are completely silent when in use. The engine brake’s principal function is to slow and stop the vehicle. When used immediately, it generates a large number of sounds. Exhaust brakes, on the other hand, make no noise and provide additional convenience on a regular basis.

How can we make the 6.7 Cummins sound more powerful?

The best way to do this is to remove the intake baffle from inside the turbocharged engine. It’s nearly impossible to come up with a better way to listen to the turbo sound. It’s a plastic hose that’s been wrapped in foam for those who don’t know.


When you know what to look for, finding the ideal exhaust for your Cummins diesel vehicle is simple. We identified the best exhaust for 6.7 Cummins diesel vehicles so you don’t have to waste time looking for the proper parts and wondering if they will fit. Because of the noticeable difference in ride and horsepower, many pickup truck owners who acquired exhaust systems from this list feel as if they’ve replaced the engine itself. Best of luck!
