Header exhaust, designed for unimpeded flow. Unlike the stock KTM header for the RC390, which has creases and dents to fit between the frame and engine, the TYGA header has been carefully fabricated to retain the round cross sectional area throughout, to avoid turbulent gas flow. Complete with Lambda sensor bung in the original position.
Compatible with the following exhausts:
Compatible with 2014-2016 KTM stock exhaust and other systems using the stock KTM header for those years.
Compatible with 2014-2016 TYGA exhaust systems EXPS-0061 and EXPS-0062
Fits on all 2017 and up 390's with an older model exhaust system.
