| Should give you a few bhp more (in the top 2-3K) and a deeper note
45/50 system will keep the midrange that you have, full 50 system will cause holes in the midrange but gain more in the top end again.
I guess it depends what you want.
I kept 45 all through after the rebuild as I like the torque as it is, and didn't want holes in it. |
