Outlining how to delete your EXUP or exhaust servo motor in.. most applications but specifically for the 07-08 Yamaha YZF-R1's.
Greatly improved ride-ability (probably due to having a faulty system initially) and the exhaust note in the upper RPM's is sooo good now too! I show the temperature difference in un-wrapped and wrapped headers and mid pipe as well as some sound clips of the exhaust note (exup delete/ stainless de-cat mid pipe & Yoshimura Carbon muffler W/out the baffles)
