Graves Quality
Very pleased with the fitment and quality. I was confused with the swapping of the long/short stacks with OEM's configuration but found the solution with Grave's official installation video: https://www.youtube.com/watch?v=hr_MqIwnT-E Video includes a rough guide on trimming the airbox lid. Otherwise you might not have clearance for the stacks to flow properly.
