I have a 2015 fatboy with screaming eagle slip-ons which are too quiet. They have catalytic converters in the mufflers. On the intake side there is a flap which diverts the gases down the side through the baffles to keep them quiet. I've tried bending the flap but it's very strong, any suggestions to get a bit more sound without replacing them?

yeah you can order or go and have a look at Cycle Shack baffles # 1547 they slot straight in an come with a little torx head allen key to the tamper proof srews holding your old ones in. the pair I did sound the same with Cat up there arse part 80639-12 I'll have to put a pic from my phone.

hey lockwood, take the baffle out and remove the wool packing inside, this will improve the sound of the mufflers
still not right for you? drill a couple of extra holes on the end of the rows of holes on the baffle or just drill a 1/2 inch hole in the flap that you tried opening
cheers mate

It's all on youtube mate , has been since just after these mufflers came out

Hilly I don't think you could remove the Cat but anything is possible? also I am unsure how far the cat goes? it is near the end pipe but I am unsure about that bulbouse looking thing a bit further along and what lives in there?? the ramp is actually pressed closed so yeah you could drill a half inch hole in that and a few more where the other holes are I just did not want to barstardize mine just in case I should ever get pinged for noise.I think the CycleShack # 1547 were about $98.00 landed here.
