    Whats the loudest muffler youve used that made good power. Seen a comments on some that actually lost power? 15 Magnum, hopefully cammed this winter.

    There is no longer a list of pipes to choose from for that bike. Now there is just “whatever I can find”

    Right now all I can get are re-cored pipes that are a 5 on the 1-10 loudness scale and Bassani mufflers that are a 7 on the scale.

    Pipes that are between 4-7 on that scale make the best power. Too quiet and it won;t make max power. Too loud and it won;t make max power. Somewhere in the middle that most consider “just right” is where you want to be for power production.

    Rylan, where are Tri Ovals on your scale regarding hp and torque? From dyno graphs I’ve seen posted, they always have that “table top top” torque curve but they give up 3 to 4 in the max Hp and max Torque numbers.

    Their sound, for me, is quite pleasing.

      Which would you say performs better: the triovals that make more power down low and up top, or the re-core that makes more peak in the middle? Hint: there is no right answer! 😀

    Yup. Regarding the Tri Ovals, my thoughts have been no other set of slip ons offer as High, as Wide or as Flat a torque curve on a dyno graph. Many slip ons offer a higher number somewhere on the graph. But, to me, the Tri Ovals offer an excellent trifecta balance of a High, Wide and Flat torque curve.

    Sound is very subjective. Again, many other slip ons offer more noise. Tri Ovals offer a well balance rumble.
