Patented Gern Pipe

The Gern-Pipe is a patented exhaust design, which has been licensed by URGE Designs. The Gern-Pipe’s key design feature is an Expansion Chamber that provides enhanced scavenging benefits similar to those seen with 2 cycle motors.  The size, shape and placement of the expansion chamber is tuned to improve the F20/22C notorious torque deficiencies between 3500 to 6000 RPMs.  We believe in full transparency with each and every product we sell – we stand behind the fact that if any of our products do not meet our strict performance and reliability criteria, we will not sell it.  While others like to provide inflated numbers by taking an untuned dyno, changing a part with. a retune to brag about “gains”.  Unfortunetly, this is a common practice that we will NEVER follow.  We only provide tuned vs tuned numbers – the stricter the controls in testing the more accurate the results.  Without those controls, dyno numbers are useless.

That said, the Gern-Pipe has the potential to provide 5-25 ft-lbs of torque gains compared to the stock exhaust system and 5-12 ft-lbs compared to test pipe and tune.  The development of this system was extensive, we wen’t through multiple designs until we achieved reproducible, tuned vs tuned, performance.

All Gern-Pipes have integrated high flow catalytic (HFC) converters to reduce emissions and improve sound characteristics.   Dyno testing has shown that there is no measurable benefit in torque or power by removing the integrated HFC.  The dyno results shown above were made with the HFC installed in the Gern-Pipe.   Therefore, URGE designs has chosen to include a catalytic converter in all of our Gern-Pipes to promote environmental responsibility. We believe this will be a growing trend in the future, since racing series such as Super GT and Endurance Racing require catalytic converters.   Note, this system is not OBII emissions legal.

Reduced Drone Acoustics

A notorious issue with most aftermarket S2000 exhaust is annoying mid-range drone.  A side benefit of the Gern Pipe’s scavenging pulses is it acoustically reflecting the sound in that 3500-6000 RPM range which significantly reduces drone at those typical highway cruising speeds.

Customer Exhaust Options

The core magic of the Scavenger exhaust system is the patented Gernpipe and thus the muffler and exhaust system is not critical to the extreme mid-range gains.  Thus, you have the option of how you want to complete your set up.

1. Integrate into your current exhaust system into the Gernpipe
2. Building your own exhaust system
3. Choosing URGE turnkey Dual or Single Exhaust systems
