I had the new SEII slip-ons installed on my 2007 Street Bob. But they don't sound as deep as the older SEII slip-ons (not EPA approved).
Is there a way I can modify them so they will sound deeper like the old ones ?
Do I have to drill holes or remove something in it ?
Anybody didthis before and if yes, how ?

Thanks

 

Look at the insides from the back.You should see the baffles bolted in place.If so they are removable.You can replace them with BCTs which from what I hear sound pretty good.

 

They have something like a screw in the side.

 

Are they the new Screaming Eaglemufflers or are they the old stlye SE II's? SOME of the SEII's will accept new baffles, not all of them. Tim

 

2 questions :

Can I just remove the baffles ?

What do you mean by BCTs ?

Thanks

 

BCT's = Big City Thunder baffles. http://www.bigcitythunder.com/pages/product-fit.html.

Are those the mufflers in your signature pic? They sure do look like Screaming Eagle Mufflers. Tim

 

Yes the're the ones on the picture. They are the new Legal SE 2's :



Thanks

 

Bobber, check your PM. Tim

 

Well, my pipes are not SE 2. It is written Screaming Eagle on them. They areEPA regulated quiet mufflers. Later on, I will change them for a new V&H exaust system. For now, just to improve the sound a little, I will try to drill holes in the baffles. If anybody have done this before, let me know if it worked OK.

Thanks

 

I don't think they have BCT baffles for the 07 SE pipes yet. I think the diameter is larger than the SE II's. You can take the baffles out and remove all of the packing and then put the baffles back in. I did and I am pretty happy with the sound. Check out this thread.
