I myself have not. I've heard stock, drilled out, atom bombs and the d&ds. There's been a lot of discussion on other sites and I think the honkers and atom bombs are very similar if I remember correctly. Those d&ds did sound good though. If I was going to spend the money for pipes again I would go for power over sound, 2 to 1 most likely. Lloydz will have some good comparisons I hope with his new filter coming out soon. He seems to try about every option, at least when the torque tubes came out he had.
