Our patented Pulse Chamber effectively eliminates unwanted in-cab droning and reduces overall cabin noise for a more comfortable driving experience. By channeling unequal-length exhaust pulses into a single patented chamber, the pulses mix, equalize, and properly balance, ensuring smoother exhaust flow. This design not only addresses noise concerns but also maintains a high CFM flow, optimizing the engine’s breathing capability to maximize horsepower. Whether used on high-performance vehicles or older models, the Pulse Chamber provides superior sound control and performance enhancement without sacrificing power.

These pulse chambers are designed with extra length for easy modification to fit your system. They are optimized for 6.0L and larger engines to enhance performance and eliminate droning when properly installed. They have been used successfully on a range of vehicles, from 900 HP supercharged cars and trucks to stock 1970s Ford trucks. MPI can also custom-build to your specifications.
