Which pipes for my F6B

[willtill]

If you are getting "Jake brake" effect, your pipes are too dam small.
You are using extra power just to turn the engine over "Parasitic drag."
All engines use power just to run, but you do not want use any more than necessary.

I was referring to felt back pressure during decel... not quite the "jake brake" effect... there is a little of it sensed with the stock OEM pipes... was curious about the free-er flowing Torque Loops and TBR's...
