To be honest its very tame until you ask it not to be. It is as loud or even quieter than my previous 107". My 96" with BSS was very loud! I have yet to set off a car alarm.

Neighbours paid the bike with you?...
If they dont paid the bike...I dont understand because you are not free to install a exhaust in the bike.
About the power....if you really want power in a Harley Davidson, buy a vrod or more cheap a suzuki m109r.

Keep in mind any exhaust isn't going to add much power.
I added wide open drag pipes to my bike and hurt performance. Loud isn't faster.
Here's a dyno sheet from S&S to prove it along with a video explaining why. Look closely at the dyno sheet and see the drag pipes underperform everywhere, particularly 2500-4000 where you ride on the highway. Even adding thumbscrews I'm not back to stock performance.
The video is worth watching too, it really explains it well.

Yesterday if someone had bet me a thumbscrew like this in my open pipes would make a performance difference I would have bet them it wouldn't.
And I would have lost my money.
1997Bagger posted up this video yesterday and I've never seen the exhaust reversion explained so well.

When I went from mufflers to open pipes I felt the mid range power loss. But they sounded so much better I've just dealt with it. I've been modding and racing Vettes and other cars for years, chasing tenths at the drag strip, so my butt dyno is pretty well tuned. I bought a PCIII tuner from Fuel Moto with a custom tune for my mods but it didn't do much, cut back on decel popping but fuel mileage went way down and power was the same so I took it off to get my mleage back.
This dyno result in the video opened my eyes. I feel that dip from 2500-4000, which is 60-85 mph or so. The lower dyno is the open pipes, then the thumb screw at 45 degrees, then 90 degrees, all compared to S&S mufflers. As you can see, the 90 degree thumbscrew gives back about 15 of the 20 foot lbs lost from open pipes. The video explains reversion in a fashion anyone can understand using the slinky.
Well, for $1.18 at home depot and a few minutes to install the thumb screws where baffles would go, I had little to lose.
I am amazed at the difference, for sure you can feel the 15 rwtq being given back by two silly thumb screws. This is right at highway mph on my bike, and the bike is noticeably snappier and pulls harder when passing at part throttle.
For those with open pipes, I highly recommend this mod. Best $1.18 I've ever spent on mods.
