I have the 70mm and i adore it. Ive had the fujitsubo on aswell.
Especially during vtec the exhaust shines, it does get annoying at times such as 3k rpm on the highway sitting in 6th gear, but that is well in the distant of my mind, when i go through the city and my car echos of the glass windows like some v8, and everyone turns and looks at this dc5r.
