So I was planning on getting the power and sound kit from bmw but we still don't have a time line of when this will be available.
Instead of waiting I'm thinking about getting the ER downpipe and was wondering if I should go Jb4 or Enzo for my tune.
What are some of the pros and cons of each. Which one would give me more power overall?
Also I do understand that Enzo is a flash where Jb4 is a piggy back tune just wanted to see a complete list of pros and cons including dealer being able to identify and such.
