the jb4 has everything you need at least for what you have in mind. FMIC and meth if you wish, but an n54 with any tune and downpipes should not feel slow.. yes compared to a built anything with a huge snail, but for any car with a tune and a cats removed? i think its pretty damn quick for just that.
