I like it, I wish you could make it functional... I also think it needs to be raised a bit too... I was going to put bullitts on my DSG, when looking for pics I found thread after thread of people flipping out against it... Do what you like that's all that matters
MY OPINION on the subject is the Mach hood serves NO functional purpose on the Cobra. it would appear to be an aesthetic enhancement, MY OPINION in this case is the aesthetic value is lower than that of the actual factory hood.
IMHO, it would actually look better to "fill" the hole in the hood / delete the shaker. cowl hoods, when properly sized, look awesome on almost everything!
