Quiet Baffle
The quiet baffles only quiet them 2-3 Db's. The bike in the pic I posted also has the quiet baffles. The main advantage is that the sound is much deeper with the quiet baffles.
I used to think the quiet baffle was the same as the stock baffle only wrapped, however I recently discovered that the design of the baffle is different as well. I am always learning new things.

From: 40 miles Northeast of Indy..
Son had BSL's on His NT... IMO there plenty loud.....
Performance wise,, here's his two dyno sheets on his 07 Deuce and 09 NT
Both had the same SE's 204 cams with 4* advance gear, and SE/AC,
Both bikes tuned by same a master HD Wrench/turner at the same dealership on same machine.. both where 4th gear, SAE tunes.
Only diff was the 07 Deuce had BR's 2-2 and the 09 NT had BSL's.
NOTICE the difference in the 2000 to 3000 rpm range between the two. This really shows that Pipes can make a big difference with basically the same built..
Note also the Deuce sheet (left sheet) that the Tq numbers, right side,are not on the same scale as the HP numbers on the left side. TQ goes to 100, HP goes to 90.
The BSL's made 70#'s at 2.2k rpm's, while the BR's 2-2 made 87 at 2.2k rpm's and was still at 86-87 when they crossed at 5200, thats a nice flat curve.
The BSL's are really nice looking pipes but seems to lose some TQ in the lower rpms for just putting around in the 2-3k rpms range vs some others pipes.
Will also add that when the NT with the BSL's started coming on the cams it felt like a four barrel kicking in.....
also U can click on the sheets to make bigger...
