Starting this thread based on Chat Box convo regarding companies who manufacturer "big bore" 250R pipes -
specifically those with a stinger inner diameter (I.D.) equal to 1-1/8" (1.125"). Standard pipes have an I.D. of 1".
With that said, please feel free to post up additional pipes until we have a comprehensive verified list. Post up what ya got and I will edit the master list. Eventually this would make a nice sticky or Tech Article.
How about FTZ, Trinity, CT, PSI, etc.?
CPI RacingCurtis Sparks- 330 HR (need to verify)
- 330 MX (need to verify)
- BB TT? (what was the actual name of this - it is hand coned).
LED Performance Engines- 350G Team
- Puma Pipe (Gen 1 - circa ~????)
- Puma Pipe (Gen 2 - circa ~ 2014?)
LRD Performance- 350B
- 350D? (?? possibly the successor to the 350B?)
- ?
ShearerNote that stinger diameter is not the only thing to consider when looking at a BB pipe. "Big Bore" can be relative - for example, ESR's TRX11 pipe is considered a BB pipe for motors up to 370cc.
