i looked for the thread i remember reading an n55 cp-e exhaust review in. i believe it's been deleted, however. it was ar design's old group buy for this exhaust. at least one person is running it on the n55, he had great things to say about it, too. sorry i couldn't find that thread, like i said i think it's been deleted now.
bottom line- cp-e is one of the best exhausts overall on the market. great power gains, exotic exhaust note, subtle styling, etc etc etc. i'm almost pulled the trigger on buying one a few times for my car
