is there some exhaust as quiet as the stock but that flow like a standar slip on?
I had the stock exhaust, but wanted a better performance.
Got the screamin eagle II, but they are too loud! and they hurt my ears in trips longer that 1 hour.
Is there some exhaust as quiet as the stock but that flow like a standar slip on?
Or at least what's the quietest good flowing exhaust option? I do't want to lose the power gains but the noise is a lot.
Thanks

It's used. Are you implying it could be broken?

The older SE slip-ons are A LOT louder than the new ones. Of course the louder ones seem to perform better also.

Could also mean the other person may have done something to the baffles.

Mine are loud 
One way to fix that is to buy cycle shack baffles and re pack the baffles... Or modify your baffles and use a "lolli pop" to control the sound and back pressure. |

Have you checked if there are gaskets fitted at the crossover? And if there are, are they sealing properly?

My SE-IIs were IMO too loud.
A previous owner had drilled a couple of holes in the end of the baffles, so I thought I'd try plugging them. When I pulled the baffles, it turns out there is an inner sleeve that's wrapped in fibleglass too. Well, only one of mine had the inner sleeve.
I ditched the one sleeve, assuming it's better to balance the mufflers. And I bought a pair of Smartpartz baffles - I saw them recommended on this forum. Now I think they are about right for what I want. Reasonably quiet at idle and cruise, but cracks nicely when you get on it.
If yours still have both sleeves, they'd likely be somewhat quieter than mine.

The current SE SP slip-ons are supposed to pass the EPA noise requirement. Any pipe passing that requirement shouldn't seem too loud. The old SE IIs did not meet the noise requirement. I know my SE IIs would sometimes set off car alarms in parking garages and I did not modify them.
