I have a 67 flh and am currently running drag pipes, I hate them they drag in the turns less power, I want to switch to a 2-1 or 2-2 setup that has a squish pipe and a muffler. My question is does the squish section have any negative effects on performance?

 

I don't notice any if your refuring to the "S" pipe which routes between the frame and engine for the&nbsp\\; front pipe.

 

Thanks Rodney, that is the pipe I was talking about.
