Yeah I found your site last night wes when I was using a search engine to find pics of them.
I found a sound file on a Japanese website of some DOHC 4 banger car with one of these. Can't read the Japanese on it, but I did save it to my hard drive. Sounds REALLY GOOD. I'll upload it tonight so ya'll can hear it.
I have the 3" Dunk on my 1st Gen DSM. LOUD!!!!!! but then again I don't have a Cat an bigger turbo. I could have got the N1 for $189 but I payed a lil more for the Dunk. Looked better to me at the time.....Till my Girl drove my car an dinged my tip
The Dunk is huge as hell tho looks bad ass from behinde the car.
