I am considering a few different exhaust systems for my 06 1500 classic. I like the look of the Cobra speedster slashdowns the best. Next would be either the HK American classic straights or the HK bad boy 3"ers. I see the new ones have reduced sound. My question: how reduced. I want a significant increase over stock, cuz stock is horrible. I like the HK over the Cobras since there are no heat sheilds also. Any thoughts on this rambling post to push me in one direction or the other is greatly appreciated.
