Hey - Sorry for the delayed response! I just noticed your post. Yes I have the KTM racing kit - full exhaust, airbox, cam and Map. It wasn't inexpensive but I didn't want to fiddle if it didn't work properly. The one thing I really like with the full Akra is it doesn't sound obscene without the db plug and I get compliments on the xound despite it being a single. You have a lot of options and now there is a power commander that can be used for tuning. I'm happy with my set up but as I said it wasn't inexpensive. Let me know if you have more questions.
