So close, but not quite. I have the N-II system.
I just went to Ark's site to make sure but here's the differences between the two for those that are curious:
- DT-S uses 2.5" OD piping vs. N-II with 2.75"
- Both have 4.5" tips but DT-S is rolled and burnt while N-II is slanted (see my avatar)
- DT-S has resonators, N-II does not
According to Ark's data, the DT-S is 90db @ 3000rpm while the N-II is 92db @ 3000rpm (unknown as to 3.6l or 6.2l for those stats)
In theory my setup should be louder than the DT-S but still doesn't seem as loud as Lil' Nasty's setup with the BBK long tubes and MRT v1.0 on his LLT. But, then again, loud doesn't always mean good (such as muffler delete for V6, it would seem).
I can't watch the YouTube videos from where I am right now but my guess at a score would be 7/10 with the N-II being an 8/10, if it were up for debate.
For anyone curious, here's a link from my HFC install, inside which is an admittedly sloppy before and after. I still aim to produce a drag run clip as well but the last time I was out I didn't get a comparable video.
