FX-1 Factory pipe: FX1 chamber vs....

[swapmeet]

I have a 61x with Factory B-pipe and a FX1 chamber. It runs great, all is well.

I know the FX1 pipe is rare/desireable because of limited production, but is there a performance gain over say, an SJ chamber???
And if so, which chamber? Limited or Mod? I've always had this setup so i've never taken the time to learn the differences in the other chambers.
NOT looking for a buyer, just wanting to better understand what possible performance differences might exist.

Thanks in advance.

SJ ltd chamber will give a bit more ooomph off the bottom....

SJ mod chamber will rev out a little bit more...


put a SJ tank and LTD chamber and you wont be disappointed

FX chamber has a nice factory "dent" on the top of the pipe near the end of the stinger
