I would go with the N1 because the price isn't worth it just because it looks "cool".
besides you can get the N1 in colors,the black matches anything.The N1 is a Great sounding muffler,I used it on my 200hp neon 2.5 striaght through,and it was still under the legal limit(nice,and deep).it was at 93 decibals,and the limit is 95.
