I was just wondering what the sound difference was between an RS Type muffler and a N1 Type muffler.

I ordered a N1 but they sent me an RS but if there isn't much of a sound difference then I suppose it doesn't matter. But one thing I don't like is the mufflers tip is like 5" long where the N1 is pictured to only be 1-1/2" long which IMO looks better.

Thanks
