CLS63/M157 Fluid Motor Union Custom Exhaust
I can't imagine what it cost to have them build this exhaust. They did one for a C63 for a "Legit Street Car" build estimated at $10K. Definitely sounds deeper... but, IMO, sounded pretty good before.

- BJ said door lock soft close would be $2500; fmu replaced the bowden (sp?) cable for $80 and charged $400 for labor
- bj wanted to do water pumps for $2000; fmu did it for $450
- bj wanted $3000 for brakes, fmu did it for $1200
my 550i has 93,000 miles (all mine since new 2016) and it's not required any significant work, anything under warranty when I had a warranty is was trivial interior stuff and a new battery




That shop as well as the detail shop that’s popular out there make me want to travel for some car care one day.
