Any harm removing baffles?

My fat bob's a little too quiet for me. Someone mentioned removing the baffles. Then to the dealer for a minor adjustment. Does this work?

What do you think of screamin eagle slip-ons? I want louder than factory but not obnoxious.

Yup, stock baffles are welded in. Only way to get them out is with a hole saw and cut the weld.

Best to go with a set of aftermarket slip fit mufflers. Try looking into a set of Cycle Shack slip on replacement mufflers from discount dealer like Zanotti HD http://www.zanottimotor.com/ .

The SE slip ons are a good choice too. Cost is more than the Cycle Shacks, and quieter than the Cycle Shacks.

Removing baffles from fat bob

The fat bob is new for 08. It looks like HD went with riveting the baffles with the bob. Unless they're also welded further inside the pipes. It would be simple to drill the baffles out.

Would I get a cracklin sound or a throaty mellow sound with the baffles removed? If crackly, forget it.

It would certainly not be mellow.

I have experience building a decent sounding exhuast for an engine with a really nasty,
and REALLY LOUD crackle, the way to cut the shrill part and get more bass was to have
an early tight, small chamber, and a final largest possible chamber, and turning it
at the end made a big difference.

Once you establish yourself as an eccentric,
you rarely have to explain your actions.

I have a Rinehart on my FatBob. Too loud, but pretty deep.

Nah. No harm in removing the baffles. I did it to my Wide Glide and I have near 2000 miles on my bike. I ran for several hundred miles and the only noticeable change (other than the sound) was a slight loss in torque. I have added a set of Xides from nightrider.com, and I love them. It took about 50-60 miles for the bike to adjust to them but I can say they really do work. You wont need to remap for slip ons, or removing the baffles from the stock pipes. As long as you don't change the a/c. In fact, the guy from nightrider.com, says if all you do is add a stage 1 a/c and a set of pipes, the Xides will handle the lean condition with out remaping or a P.C. III or, any other type of fuel processor. Have a look into the Xides, they are a great product.

My 03 low rider is without baffles, courtesy of the previous owner my brother-in-law. I am planning on putting on the SE slipons. Will this correct the overly lean condition? Will I have to rejet or can I just adjust the air/mix screw and be set to go?
