Good group of guys there, they specialize in FI and have built some mean Bimmers (see website). They do all types of installations and exhaust modifications (pipe bending, welding, muffler delete, cat delete etc). They recently installed a dyno too.
Ask for Mike, tell him Anthony from across the street referred you.
