would appreciate if i could get someone could share their experience with the different combination of nova pipes/header to suit the 4btt n bonito.

I run the 2096 with the 41021 on my plus 4, very smooth, great top end and run time. Some have reported good results running the 9901/41001 header but I havn't tried that combo yet. What sirio pipe are you using? my plus 4 liked the 2058 but I found the 2096/21 to have the same top end but better run time.
