* MBRP (Midwest Best Racing Products): Known for offering a wide range of exhaust systems, from relatively quiet options to very loud ones, at various price points. They often provide a good balance between performance and sound.
* Flo-Pro: Another popular brand offering a variety of systems catering to different preferences. They are generally known for durability.
* Diamond Eye: Often praised for their quality and performance gains, particularly for those focused on horsepower and torque increases. They can be on the louder side.
* Banks Power: Banks is a reputable name in the Cummins performance world. Their exhaust systems are often part of a larger performance package and may be more expensive.
* AFe Power: AFe offers a blend of performance and sound, with options ranging from relatively subtle to aggressive.
System Types to Consider:
* Complete Exhaust Systems: Replace the entire exhaust system from the turbo back. These offer the most significant potential performance gains and sound changes.
* Cat-Back Exhaust Systems: These replace the exhaust components from the catalytic converter back. They offer a noticeable sound change but typically less performance improvement than a full turbo-back system.
* Muffler Replacements: Only replacing the muffler is the least expensive option but offers the smallest performance boost and sound changes.
Factors to Consider When Choosing:
* Sound: Do you want a deep rumble, a throaty roar, or something more subtle? Watch videos of different systems on YouTube to get an idea of the sound.
* Performance: How much of a horsepower and torque increase are you looking for? Turbo-back systems generally offer more gains than cat-back or muffler replacements.
* Price: Exhaust systems vary widely in price.
* Legality: Check your local and state emissions regulations before purchasing. Some aftermarket exhausts may not be street legal in all areas.
* Truck Year and Model: Exhaust systems are specific to the year and model of your Dodge truck and Cummins engine.
Recommendation: Research the brands mentioned above, focusing on systems designed for your specific year and model of truck. Read reviews, watch videos, and consider your priorities before making a purchase. Talking to other Cummins owners in your area can also be helpful.
