One thing about Jackpots is that they come in a few variations. I opted for Jackpot Classics (Slash up) with 2.25" baffles.....that variation is far from what anyone would call "too quiet".

 

I have the PC-V and Dyno Tuned Jackpots. Performance is quite noticeable right from the start. Haven't had enough riding time due to chitty weather to tell how much of an effect it has had on mileage. Sound-wise they are a little quiet for my tastes, but they are growing on me. Hope they will get a little louder over time like some people report. Now my wife says they are plenty loud. She can hear me over a mile down the road. Says they are a little deeper and bassier than my olde Rineharts. I will agree on that. Similar to the Rineharts. Just a little deeper and not as loud.

 

Suggestion when comparing your sould levels, please note which size baffles you have in both right and left mufflers. Both the rush and jackpots have choices that will either make em louder or quieter. When ya say "they are not too loud for me" and we don't know if ya have 1.75 or 2.0 or 2.25 baffles, its kinda hard to tell exactly what you are talking about. Just a suggestion!

 

I Installed the jackpot dyno tuned baffles in my Kerker mufflers and used fuelmoto's map,and SE air cleaner I love the sound, deeper than the stock Kerkers with about the same volume.
I was concerned with fuel milage .I live out in the country and don't have much stop and go so I was getting about 44mpg. I have run through about 3 tanks since the new set up and I am still getting 43. I also notice it seems to be running a little cooler than my old set up. All in all I don't think you can beat this stage 1 set up
