I have a standard Two Brothers slip on and I was thinking of converting it to a highmount. Now my question is, I like how the M4 highmount follows the lines of the bike better than the Two Brothers midpipe. Would I be able to use the M4 midpipe as long as it is the same diameter? Also if I were to use the M4 would it hurt performance any compared to the Two Brothers midpipe? Thanks in advance

 

As long as the diameter and mounting is the same. Some use clamps, some use springs.

Don't worry about power. It won't make a perceptible difference.

I have a Scorpion can on a Hindle High mount pipe. Works fine after some tweaking on the mid-pipe diameter. (pipe expander)
