i'm thinkin about getting jdm 4-1 and an a'pex n1 exhaust for my type r. i already have an aem cold air. i've really been studying piping diameters and reading a lot of tests, specs, and reviews. i also love spoon so i've been following along their philosophy. spoon's b-pipe is 60.5mm where the a'pex n1 is 60mm. i'm not looking for something outrageous, but something a little better than stock and that doesn't put a hole in my pocket. i'm probably going with the jdm 4-1, and the n1 exhaust i like cuz of the piping dia., sound, and look.

what do you guys think? any feedback will do. thanks.
