New Fatboy that I bought the V&H 3" slip ons, Fuel Moto intake and PC V that Fuel moto loaded a map in it. I put just the mufflers on 3 weeks ago so I could hear the engine and a bit loud and harsh sound. Pretty significant decel popping. Today after the 1K service, I completed the stage 1 and also put in the quiet baffles. Baffles are not the easiest thing to get in but using a suggestion on this forum to tightly wrap the fiberglass with fishing line helped get it in. The other baffles fell right out when I removed the screws.

So now the bike has the same mufflers with the quiet baffles, FM intake and the PC V with their dyno tune for the equipment installed. Some minor decel popping but greatly reduced. Sound is reduced and not as sharp or harsh. Only put about 20 miles but seems cooler also. Seems stronger also.

Happy with the results.
