STE-2 for European and Australian mufflers. KTM only
These fit 2015-17 stock mufflers from countries other than the USA and Canada. If you look in the tip of your muffler and it has a perforated metal cone in there, then this end cap will fit.
The stock outlet size is 28mm, the STE-2 outlet size is 34mm and fits around the core as well. It offers a huge gain in performance from bottom to top, over the stock end cap. It also has a quiet insert, which an easily be installed for motoring through farmers fields. Installs in minutes. Using our TPS tool afterwards to get the fueling correct is recommended and a nice gain in response and power as well.
