K&N is blowing smoke if they think their smaller filter will make 30hp over stock. I went the aluminum pipe route but wanted to make sure all the factory mounting locations were utilized. Took a couple hours of design and fitment but I think my intake came out pretty nice. I’ll probably sand out the grinding marks and cerakote it black if I don’t have any issues after a couple weeks. As for the sound, the turbo noise is substantially more noticeable over 2500-3000 rpm. Anything under that and it sounds completely stock.
