Custom vs Prefub Exhaust



Can use some advice and direction here

Thinking about replacing stock exhaust in my '10 CL63 but can't decide between custom built and prefabricated.
There is significant difference in price between the two, so obviously there is a lot of difference...
What do you guys think? What would you go with?
Any recommendations on either manufacturer of the prefub or a good exhaust shop in LA area?
Your help is HIGLY appreciated!
