Jackpot Baffle Sound dB testing by Fuel Moto

Here is some information on some recent dB tested we have performed for our Jackpot Dyno Tuned mufflers along with the optional Jackpot Competiton baffles and Jackpot Tunable Quiet baffle. These tests were performed using SAEJ2825 test procedures using a JTW digital sound meter. The test bike was a 2009 Touring model with stock headpipes and Stage 1 air cleaner.

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

There is more info on this test procedure at http://www.mic.org/news062409.cfm

We developed a couple of baffle options for the Jackpot Dyno Tuned mufflers. The first is the Tunable Quiet baffle for those looking for a very quiet exhaust. This baffle features a Stainless Steel chambered core and includes a "Silent Insert" which can be easily removed or reinstalled. With the insert in the mufflers are near OEM sound levels with a nice deep tone, while removing the insert gives you a bit more sound at a mild dB level. The other baffle we developed is the Competition baffle which provides maximum sound with a deep aggressive tone. There is more info on the baffles at www.jackpotmufflers.com/accessories If anyone has any questions just let me know. Here is a picture of the Quiet baffle with insert

We have a ton of dyno info on these baffles. I will need to go thru everything and put together charts from baffle testing we did on the same day, same conditions etc.. I will try to get something on the site this week along with some charts for our Jackpot 2/1/2 Headpipe

That is some valuable information...something that you don't often see from exhaust manufacturers.

Jamie Can the quiet baffle be used with the Jackpot dynotuned mufflers/baffles? Is the quiet baffle only used on the right muffler? Will you have a PC3 map available for the quiet baffle. Thanks
