Moto X, a German dirtbike magazine just did a test on a 426 YZ to compare all exhausts.
The following is just a resume of the article:
Not in the test because no exhaust available or not wanting to participate:

Dr D, PC, Lazer, SPES, Doma, White Bros, DSP, Yoshimura and BIG GUN.

Stock:

45.7 HP @6600rpm (at wheel I think)
42.8Nm @6600Rpm
3.3kg

Akrapovic:

48.1 HP @ 8900rpm
44.6NM@ 6250 rpm
2.3 kg

DEP:

47.3 HP @ 9100rpm
41.5NM@ 7200 rpm
2.9 kg

Gianelli:

45.8 HP @ 8000rpm
43.9NM@ 6400 rpm
3.4 kg

Arrow:

46.8 HP @ 8350rpm
43.7NM@ 6600 rpm
3.4 kg

LeoVinci X3:

46.7 HP @ 8900rpm
44.0NM@ 6600 rpm
3.4 kg

FMF Titanium powerbomb

46.7 HP @ 8950rpm
43.9NM@ 6350 rpm
2.5 kg

The mag was very positive about the Akrapovic, and from my experience on road race bikes, these do work well.
I just think it's a shame no more USA brands were in the test, that way I would know where our European brands are compared to what you guys are riding.
I think I might get myself a Akrapovic system, I'm just unsure how to adjust the jetting if needed. Any help is welcome
