Hello.
I'm going to make a couple upgrades to my 545i: I know I want to do the Dinan software upgrade: not sure which stage (I, II, or III) to do. I want the faster shifts and added performance. Any advice?
Also, I'm going to put an exhaust on it. Originally I was just planning on a Dinan after cat system for better sound, now I'm also thinking about the RPI, as it's cheaper. I also have read a number of threads stating how nice it is. Which one would you go with? RPI: cheaper and good sound, quality, and fit OR Dinan: good sound, quality, fit, and the dealer can order it and install (one stop shopping). So... Which would you go with and why??
Thanks for your input.
