On my 13 I put the black Show Chrome with the round vent holes. Yes it scraped, followed shortly by heat shields and the front crash bars. On my 14 I went with the louvered stainless and painted it black. Why did I go with a different pan you my ask. The one on my 13 was aluminum and used very small hex head screws to hold the front part in place. The small steel hex head screw was easly stripped. Steel and aluminum don't play well with each other. The stainless pan uses 1/4 turn aircraft fasteners. As for scraping. When I get to the edge of the belly pan I am also getting to the heat shields. If your going to go with out a pan I would put something more than the aluminum duc tape that Honda put on the overflow tank. Lastly when I installed both pans there was not more than a 1/16" from the engine block.
