The 2-1 with teh 2.5 baffle would work fine, Now here is a 113 600 cam zilla pipe NO head work with 58 TB , as you can see it still has good low end even with the perforated core baffle which I am not a fan of
I think I remember when you posted this graph on another thread where you said you were impressed with that tune. I'm not a fan of D&D as I dont like the sound, but I do like the Dragos 2-1's. My riding buddy from FLA runs the Dragula 2, and I like the sound of that, and its reputed to perform well.
I was thinking about going 2-1 awhile back, just for a change really. At the time, I was leaning towards the non- stepped version, as I thought it tuned easier and was better for low end tq.
The bonus is a new 2-1 wont cost me anything once I sell my 2 sets of mufflers and headpipes.
If not, Im glad to hear my DX and Rineharts are a decent set up after all. Ill have to give this some thought.
