I have 4-1... I've been told by exhaust people (so who knows really) that 4-1 are better at high rpm, while 4-2-1 have more back pressure and therefore are better at lower rpm, but restrict a little at high.
So it depends on what you want really, personally high rpm is good.

| I'm guessing tuned length means the headers are the same length from the exhaust port and where they all meet? In that case, mine are tuned length. |

my 4-1 had better low to mid range and my 4-2-1were better for top end but i had a 21/4 inch with the 4-2-1
and a 2 inch with my 4-1 that may have made a difference

| they get in the way, you have to tie them back really tight to the shock tower with rope or you bash the brake resivoir... |
