Towing - Recommendation
If you frequently tow heavy trailers over long distances with large-engine trucks (6.0L and larger), we recommend choosing the MPI Turbo Series. Our patented pulse chamber ensures a drone-free experience while towing, allowing us to focus on fine-tuning the muffler to achieve your preferred overall sound profile.
Which Muffler Delivers the Most Horsepower?
The MPI Muffler series can be interchanged within our MPI system based on sound preference, while still maintaining the high CFM range and volume required. Despite their unique configurations, both muffler designs provide almost identical performance, differing by only 0.70 horsepower. All dyno results are obtained using the MPI Performance Series to ensure consistency.
Bullnose Series - Sound
Our MPI Bullnose series uses MPI’s Performance Series mufflers to produce a bold, aggressive tone. By placing the signature turndowns in front of the rear end, the truck bed functions as a speaker, resulting in a deeper and more aggressive overall tone.
