Hi Houston,

I have a backup P5XS (2008), and got it from a buddy. I am running a STRR, on medium size tracks. It has been a long time since I ran a P5.....what is a good restrictor to use (7 or 7.5mm?) and pipe for my tracks? I have a 2050, JP2, Dynamite 53, Dynamite 86, and MSR1005 pipe. I have a long header, a Dynamite header, the stock T2050 header, and what I think is a short ] shaped header (pretty sure it came from the MSR 1005 pipe, but it has been so long, I am not sure).
