Hi Peter thanks for the input. I didn't think of doing a db test on the bike due to wind noise and distance/location from the pipes but at cruising speed the bike is quite sedate but crack the throttle and it's an angry sound but not as loud as a loud HD.

No the shorter baffle fits the same as the standard one,no mods necessary.

Hi V Star Thanks for the comment. We live in a very strict Province (=State in USA) that is very hard on bikes with noise emissions and NON OEM pipes so to fly under their radar the quiet baffle was installed which lowered the db and tone to just legal levels. To lower it further I would install www.dkcustomproducts.com/thunder-torque-inserts-258-model-family-dk-tti-258.htm and experiment till I got the balance between Sound and Performance (usually the two are at the same point in adjustment). My phone takes great pics but is lousy at recording sound and unfortunately that is what I used to capture the sound on this video. So to conclude I felt the investment in the extra baffle was a good purchase since it allowed me to experiment with one while the original sat on the shelf incase my experiments on the other rendered it trashed.

The sound was deeper and not as sharp sounding. The baffle was recommended by one of the factory service reps. Its an 8011 There is also a co that makes a version of the adjustable lolly pop that fits in the baffle about 2.5 to 3 inches from the exit

Wheni talked to the factory the person called it a quiet baffle but said it wouldn't be lower in volume but would give a lower tone. This is exactly what it did in addition to getting rid of the raspy sound. I also noticed that it had two personalities. If you were in the city going easy on the throttle it was quite reputable but anything beyond light throttle, you just woke up a monster, very nice deep thump. Yes that is the correct number that you listed.

B2011?  I can't seem to find part # B2012W anywhere.

No difference in the seat of the pants power evaluation. I did think about fine tuning it with a lollipop/ washer setup.

@@brianmchale2926 thanks for the reply i'm gonna try a bassani quiet baffle on my sportster to try and make my neighbors happier.

When I talked to the factory support desk I was told that it gives a deeper sound but that it reduced the db slightly. If it is the performance baffle then I am in the dark about that. But I did like it more.

@@brianmchale2926 I'm not sure that the quiet one will fit the short pipes but it'll fit the long one it's 22inches long for the quiet baffle

Get some aluminum exhaust tape and tape over one fifth of the holes on the baffle tube. You will have to remove the fibre glass and reinstall it after. Try that and if you need to, block off more.

Thank you man.

@@tonyvancauwenberghe3171 no probs.

Actually the stock baffle is longer and lightly packed. The accessory baffle is shorter.

@@brianmchale2926 thank you, don't remember the thickness of the factory packaging?
