Only you can decide if you should do it or not.
"1. How is the performance, fuel economy, noise, requirement for 92+ octane fuel, reliability, etc."
Check the link below for some performance info. Fuel economy drops a mpg or two. Noise is about the same. Reliability looks good so far. High octane gas is a requirement.
"5. Did you do the modification yourself - if so, would you recommend self-installation? How were the
instructions supplied by D/A and did you encounter any other expenses or require supplies that weren't included in the kit?"
Yes, there instructions were very well done overall. The kit includes everything... even wire ties and locktite. All you need are the tools.
