Silent Might™ mufflers

Looking to annoy your neighbors in the middle of the night? Go shop elsewhere!

Have you already switched to a "mellow tone exhaust" only to find it giving you a headache? Have you gotten a noise citation?

Do you hate to give up the higher performance by going back to stock? Read on!

 

Developed by an acoustical engineer, this patent pending tuned resonator type muffler was optimized for the difficult to tame low-RPM Cummins inline six. A 9-inch diameter body, 41 inches long, with 4-inch inlet/outlet straight-thru design (48 inch overall length), it fits neatly under your Dodge or Winnebago. 

No other muffler anywhere provides this performance. Standard truck mufflers (Donaldson and others) have typical restrictions of one PSI (2 inches mercury). The stock Dodge muffler backpressure can go as high as 2 PSI at high RPM. 

Thanks to careful tuning, this muffler has less restriction than a straight pipe in the range of 1600-2800 RPM on a six cylinder engine.

Complete instructions are supplied with the Silent Might muffler.

 Adjustable Timing Sensor (5.9 & 6.7 common rail Cummins)

This crankshaft sensor perfectly replaces the stock Cummins sensor, allowing for adjustable timing without codes or a voided warranty.   

Adjustable up to 2 degrees, in 0.1 degree increments, it improves mileage, increases torque and power, reduces exhaust temperature, and reduces greenhouse gases and smoke (even with larger injectors).   

Undetectable, will pass emissions testing.  Includes instructions.

 

Most people need about 5 minutes for installation, mechanics about two minutes.

Made in USA

You do not need special tools to set timing, and do not have to worry about damaging "knocking".  It will simply not allow timing to become so far advanced as to cause any damage.  If you plan to use it with aftermarket timing altering software or hardware click here.

Pays for itself in fuel savings.
