i've had my N1 Dual and pro-kits for almost 2 years and honestly i hardly ever scrape (maybe 2-3 times total, all on steep driveways). I also use common sense like slowing down for speed bumps and such but i scrape the front spoiler on my sisters civic all the time driving the same way i drive my 240. i really don't see why people think they hang that low, the single N1 on the otherhand i can see would have some problems... If you still don't believe that i don't have scraping problems i'd be happy to go outside and take some pictures of the exhaust
EDIT: actually i scrape a bit more now... but thats due to my horrible fitting hotshot header and its still not that big of a problem. hopefully i'll be getting the header adjusted soon
