Surprisingly quiet compared to most. Lots of power gain with PCV and Fuel Moto tune. Doesn't interfere with stock SG stereo at all. Sound is objective but to me they were about twice the sound of the stock exhaust on a new 09 SG. Hated to do it but had to go back with the Rineharts. I'm not a quiet kind of guy.
These DB numbers were originally posted by Fuel Moto and show the Competition Baffles are loader than Rhinehart and Rush mufflers.
Has anybody who heard the competition baffles agree that they are loader?
Stock mufflers IDLE 78.4 dB SET RPM 90.9 dB
Jackpot Tunable Quiet baffle with Silent Insert in IDLE 81.9 dB SET RPM 91.7 dB
Jackpot Tunable Quiet baffle with Silent Insert out IDLE 83.6 dB SET RPM 92.5 dB
Jackpot Dyno Tuned baffles IDLE 83.6 dB SET RPM 93.9 dB
Jackpot Competition Baffles IDLE 89.3 dB SET RPM 100.3 dB
Jackpot Carbon Billet mufflers IDLE 84.5 dB SET RPM 97.8 dB
For Comparison:
Rinehart Slip on mufflers IDLE 84.6 dB SET RPM 98.9 dB
Rush slip on w/ 2.00 baffles IDLE 84.2 dB SET RPM 98.2 dB
just installed mine last night, db level is louder than the dyno tuned but IMO you lose some of the low bass note rumble, I can still her the radio fine on the ultra.
maybe after I can get the head pipe and get ride or the cat some of the rumble will be back, right ow sounds more like a loud glass pack than the thump of a harley.
