Exhaust Shops in Sterling VA area

Hey everyone. I just purchased a new set of Chrome Shorty headers and wanted to know if anyone knew of a good reliable wrench shop that would help with the install? I would try it myself but what I hear, you need to have atleas 3' to 4' feet of clearance below in order to install.

I live in Loudoun County VA near Fairfax VA....Specifically, I live in Sterling.

Thanks everyone,
Joey
