LO2W 👍👍Finally a comprehensive and legitimate sound comparison video. After about a year in pursuit of the right exhaust system application 2020 390 Duke (high pipe, left side), I'm closing in on it. Please Help 🙏 After 55 years, countless motorcycles, countless miles off road, on road, on track, competition, and recreation riding I decided to buy a 2021 390 Duke that I retrofitted with OEM 2020 KTM 390 Duke exhaust header. Fast forward past hours and days of research, my Yoshimura Race R-77 system is now installed, cat delete, no pre muffler and Sound Insert INS-27-K installed. Time and money being irrelevant, the bottom line is Obnoxiously Loud. I've already spent hours and days this week searching for specific part numbers and a source for the Full Arrow system featured in the video between 0:24 and 0:50, with pre muffler, preferably no catalytic converter. I have the official Triumph accessory Full Arrow exhaust system installed on my Triumph 675R and it's one of the best I've ever owned.
