I'm a little west of I-95 on rt. 32 north of the DC beltway. Are you closer to Rockville or frederick?
If it's frederick, the quickest way to get to me is on 70E to rt. 32 and then I'm about another 10 minutes east.
If it's Rockville, the beltway to 95N to 32 W and in decent traffic it should only take you 30 minutes. I drive to work just off the last exit in MD on the west side of the beltway in less than 30 (but it's at this time of the morning, I'm at work now).
Either way it's definitely close enough to be worth a free exhaust! Let me know when you want to get it and we can work something out, my schedule is a little hectic right now, but I need to get rid of it.
