UEL Header Emulation (UELHE) Custom Feature

NAMR custom feature, available through GropeTuned, an official Atlas commercial tuner.

NAMR feature description

Months of research and development and countless combined reliability testing miles across our fleet of beta and development vehicles has resulted in us releasing an exciting feature for the FA-powered WRX: UELHE.

Bring back the Subaru rumble with NAMR’s unequal length header emulation on your FA-powered WRX! UELHE replicates the sonic exhaust character of an unequal length header to not only fully unlock your WRX’s rumble, but preserves performance by blending back into an equal-length operation envelope in wide open throttle.

You can now experience the best of unequal and equal length exhaust headers with just a software tune!

To install the Custom Feature, please follow this guide.
