I like the look of the Mercedes engine cover and the dcai. And any gains would be welcome as well. It's something I can build myself as well so it shouldn't cost me a whole pile of cash. I just need to figure out what I need. If I can get my hands on a 74 mm maf and y pipe the rest will be a snap. Worst case I could build my own y pipe but why reinvent the wheel if I can find one at a reasonable price.
