just got my 0801 pipe today already on the buggy and i ran a tank with it sounds and runs great. I have it on the 7 port turbo. I also got my 3 port race today also. I was running the 7 port with a os 2050 and i thought that it ran great what kind of differences should i see with the 0801 pipe. Also wondering the biggest difference between the 3 port race and the 7 port turbo. Both of my engines are the 08 version. thanks guys.
