I spent a bit of time and research trying to decide the same thing. IMO...the cleanest option for the newer monsters is the Motodynamics fender eliminator (FE) + their integrated taillight.
Here's why...
1) No blinkers sticking out with integrated tail - sequential turn signals and stop alert feature are cool and functional
2) Relocated key hole means no fugly box sticking down creating a "flush" look with the subframe...you don't get this with evotech and others
3) The FE is only $30!! Integrated taillight is $75. So basically get taillight + FE for the cost of the Evotech FE
4) No other combo will yield this look at this price that I am aware of. Correct me if I am wrong please.
Downside: on 796/1100 you need to eliminate the servo motor with Duc.EE or deal with a CEL. That is the downside of benefiting from the flush look as the servo motor mounting plate hangs down below the subframe when viewed from the side. This is not a problem with 696 obviously or if you already have ECU/exhaust with servo removed.
I have no affiliation with any of these companies, just my .02 from my own research. Hope this helps...
did a quickie peak at the install instructions, and it looks almost identical to the comp werx kit
