I found that I was hijacking HiLiners thread so I thought I would start another. I know everyone says the Dragula sound, quality and fit are great and also that Frank is great to deal with. What I am looking for is numbers info. Real data that says I had brand X and when I changed to the Dragula, I picked up X amount of tq/hp on the dyno and I don't mean the "seat of the pants" dyno. Also interested in where the differences were (low/mid/top). Looking for all reports, good or bad. Thinking about changing my BUB 7 system with crossover that I have run for 4 years.
