Pimping up your 5.9L Cummins engine with an aftermarket exhaust system will definitely add some performance improvements as well as give you that loud rumbling roar that will make late night stealth rides a thing of the past (Unless you install a muffler).
Yup, you will no longer be driving around in a nice quiet suburban attitude, it’s time to get all Republican and have a loud-mouthed red-neck exhaust system, and I say this with pride. On the other hand, if you live in the suburbs and you need to keep quiet, consider a muffler, it will help you even if you are a loud person.
There are many brands out there, and you can get some great made in the USA models.

4. MBRP Single Side Exit Cat-Back System
XP Series Exhaust System
- 2004.5-2007 Dodge 2500/3500 for Cummins 5.9L
- Single 4″ Side Exit
- Cat-Back
A high-quality exhaust system, the MBRP Single Side Exit Cat-Back Exhaust System, is made of T409 stainless steel and has a T-304 steel exhaust tip. This means it’s going to last longer and fare better than most other cheaper exhausts. But that’s not where its advantages end. It’s a single side-exit unit that can be fitted to the catalytic convertor.
In terms of the exhaust note, it’s said to have a rich, mellow one. It’s perfect if you don’t want an excessively harsh exhaust sound but are done with the unimpressive stock exhaust system. In addition to that, mentions MBRP, you can also get a power increment of up to 18 hp since the exhaust enables the engine to perform better.
It can be fitted straight in place of the original exhaust with common tools. The factory hangers can be utilized, and you won’t need to do any modifications to accommodate the MBRP system. It won’t require you to do any welding either. On the whole, the installation should ideally take about two hours.
It’s backed by a lifetime warranty and is compatible with the later-model 5.9 Cummins Dodge Ram trucks (2004.5 – 2007). You can check with the seller about the warranty and any other questions regarding finer compatibility. Users are happy with the way it fits and sounds. Owing to better materials, it’s more expensive than other aluminum models, but it’s a one-time investment, so it’s well worth it, we feel.
5. MBRP Aluminum Cat-Back Single Side-Exit Exhaust
No products found.
If you’re looking for a more cost-effective exhaust system from a reputed brand like MBRP, the MBRP Aluminum Cat-Back Single Side-Exit Exhaust is worth checking out. It’s a 5-inch exhaust system made for the 2004 – 2007 5.9 Cummins engined Dodge Ram trucks.
Made of aluminized steel, the exhaust system has a 5-inch tubing, large-radius mandrel bends, and a free-flow muffler design. The two-piece tailpipe doesn’t include a muffler or an exhaust tip. You can purchase the latter from MBRP for an improved and complete look.
It’s one of the more affordable options, and the difference between this and other ‘Pro’ series models is the use of aluminized steel instead of higher quality material like stainless steel. However, it still sounds decent and benefits from good craftsmanship.
It can fit the Quad Cab Long Bed or Mega Cab models, but it can be trimmed as per your requirements as well. To ensure you get the exhaust that fits your truck perfectly, drop the seller a message before buying and enquire about the correct model. Confirm with the seller about the warranty too.
