For the .25 6 port use the 086 its the recommended pipe other than a Go pipe, the OD97T or 77T is good or P3 or P4. The guy with the 3 port race, the ae2035 this pipe is similar to the 053 I run on my 3 port BUT mine is modded. I never will tell someone to put a JP pipe on a GO engine unless you dont care at all about runtimes. I am not going to disagree with anyone so I am going to say try them both. JP pipes are awesome pipes but for some reason they get shitty runtimes on Go's. I have tried the 1 2 and 3 and they ran well but I got like 3-4 mins of runtime with other pipes a midrange pipe isnt a bad choice for the 3 in stock form I know a GO now EB sponsored guy who used to run either the 2060 or 2050 on his 3 and swore by it and had many pipes to choose from.
