Stop in for a cup of coffee

Mornin peeps. Finally got the Duster out for a ride just now. First in a LONG time.. Just several miles down the road and back. Started great. Ran great. Still seems way loud (not really a good loud either, lol), just before it upshifts into highest gear. Thinking its an exhaust resonance thing, but has an odd vibration with it. Then I got stuck behind a slow poke with a small trailer coming back and it was going in/out of that range. :BangHead:
