Hey guys I just got a 2013 ST-R last friday and my Arrow exhaust came in last night. I haven't found information where any has taken the DB killer out yet. The screw was tack welded in, so I took a dremel to that and backed it out. The hard part now is trying to find away to pull the DB Killer out. My local dealer told me they made a special tool just to do this. I as checking to see if anyone else figured out an easy way. I will report back with my findings as well.
PS Arrow exhaust installed in minutes (you can easily do this in under 10 minutes with a 10mm, 12mm, and pliers. Perfect fitment
